# Prime

We were given very simple definition by our teachers about what is a prime number and it was “a number not divisible by any other number except number 1 and itself is prime”. It was a cool definition. Let’s think about it bit differently.

Imagine a unicorn which can only jump 2 places and is standing on apple nbr 2. If we let unicorn run on below apple road how many apples will it crush ?

In first jump it will crush apple-4. And it misses apple 3. And further it will crush 6,8,..

Let’s put a rule, for every jump if it cannot crush a apple – apple becomes a unicorn of that number. And that unicorn then jumps with earlier unicorn. But here the jump length of that new unicorn is the new uncrushed apple number.

So we get our first new unicorn nbr 3. Now if both make jump we will see below :

They cannot crush apple nbr 5. So we get another unicorn of number 5.

Now if all of them makes jump, we see they all cannot crush apple 7. All other apple get crushed.

What have we seen so far?

Every unicorn that gets created due to apple not being crushed, is a prime unicorn. 3, 5 ,7 numbered unicorn are all prime unicorn and are the prime numbers below 10.

We only needed unicorn 2 ,3 and 5 to find out if there are any other prime unicorn below 10. (this modifies our initial definition, we don’t need to divide a number by every other number, but instead every other prime number before it (but hold on to it as well for future blog)).

ie. we found that a apple becomes a unicorn if it does not come under the cycles of earlier unicorns.

So we can refine the earlier definition to “A number is a prime if it cannot be divided by primes smaller than it. And 2 is a first prime.”

Important question remains – how we chose our first unicorn. Why was that unicorn numbered 2 and not 1 or 3. My answer is – it is how humans think. We make assumptions to create beautiful problem definition. If we have chosen first unicorn as 1 then, no apple would be left and then no unicorns and no prime numbers.

And now humans are still finding all those big unicorns which are apples and could not be crushed by earlier unicorns. As of Today the largest found prime number is mentioned here.

For ref, below is the further sequence from above concept. It generates unicorns of 11 13 and 17 value.

# Opening the door

Parents use some tricks for kids to NOT do something. One of such things is when parents do not want kids to go to certain room in the house or place they will tell that there is ghost inside that room , don’t try to go there.  This trick works but it creates curiosity in kids to know if really there is ghost, but out of fear they wont try.

Here there is fear which stops kids to explore the hidden area.  Some kids dares to open it and to their amazement there is no ghost :).

In my life I had never run 5km in one go. In school times we use to run race for 100m,200m etc but that’s it.  I didn’t know yet what would happen if I run for 5km non stop.  On trade mill I ran some distances but amount of energy and strength you need on the road is very different for sure.

I didn’t run long distance in one go may be because of various reasons. First, I do not  know people who do it regularly. None of my friends, colleagues or relatives have done it, neither its in my culture. So I was unaware of such things. Second, I do not know why should one do it. Other reasons such as no time to do it , no place to do it etc. (fake but self excusable reasons). Also I see some people running on the road and they are already fat so it’s clear that running even wont help to reduce weight(this is probable case, 7/10 running people,in my view, on road are fat as they are running to reduce the weight) .

I realized that running long distance (minimum 5km) is a such a closed door (closed by none other than me) that I never explored.  And real reason I found that I do not have curiosity to know what will happen if I run such distance. Probably I thought nothing will change in me(just a guess).

In month of Dec 2018 some event happened which ignited me to run at least a km per day.  So starting this year 2019, I started running 1 km everyday no matter what.  Incidentally there was a Marathon (5km) in my community in Feb and I thought why not run it.  To my amazement I ran it.  I happen to open this door of running for long distances.  I think this will change me by greater value.  For sure it benefited me as weighing machine shows a good difference in just a month time.

I think there are many such doors that one need to open to explore oneself.

Namaskar – The ultimate bow down !

You are going down from the top of a very tall mountain using a bike. The road is okay except it’s a slope. The mountain is very tall and the journey could be very long. Due to the slope, the speed of the bike would increase on it’s own.
You are very unfamiliar with this road as you happen to be on the top of the mountain by some other way. The first aid is available only at the top of the mountain.

One of the best approach to ride the bike in this situation would be to apply the brakes at regular interval. Especially if you are busy watching mountain beauty, the habit of braking regularly will make your journey smooth. If you forget to apply the brakes before the speed of the bike becomes uncontrollable, you will hurt yourself and the rest of the journey will not be so good, sometime you got to start again from top.

One carries a pride of being someone or doing something with him all the time. I am a xyz manager or I am the best xyz player or I am the best Son among siblings or I am the best at making business or I run this house of my own etc. all of these are same at the root level of mind and that can be called as ego.

This ego is a continuous flow of thoughts (mostly unconscious) which is running down the hill with your mind(bike). It runs by its own gravity pull and if you don’t brake it it will surely hurt you badly. Sometimes so badly that one has to begin the journey again. This journey of life(climbing down the mountain) is very unfamiliar to you and mostly things happen without you being conscious of it. You are busy earning your survival so much that you forget that the the bike is crossing the speed limit. Applying brakes at regular interval surely is a solution.

In my culture we have been taught (samskara -संस्कार ) to do Namaskar (bowing down) to elderly people by touching their feet. Touching the feet means “whoever I am, whatever I have achieved , it is grounded (zeroed) at your feet. All the pride that I was carrying till now, I ground it at your feet”. This is the brake; the brake that one can use to slow down the ego flow.

We do namaskar to God idols, saintly people, elders etc. This bowing down helps to nullify/reduce the flow of your ego. Anyways, sooner or later, time will swallow you and everything you have. Letting ego swallow you will be a foolish act. It is wise to let the ego slow down at regular interval.

# Pooja ( पूजा )

This post is not about person named Pooja but is about the actual meaning of this word which is “a regular and disciplined act of spending some time doing certain actions such as cleaning and decorating(with flowers) idols and the place, chanting some shlokas, praying God, and all this with complete attention”. Regularity has the higher importance followed by one’s attention, followed by the actions performed while doing Pooja.

A person between age 30 ~ 45 is more conscious than he is during other age years in his life. During these years he understands more deeply why he is doing the things that he is doing. And in these years he gets surrounded by his own making. Often he gets stuck in the process so deeply that he starts suffering his own thought process. He starts looking for a way to untangle this rope, the rope of thought process, that he is tying himself.

One idea to avoid the pain of this entanglement is to first stop further entangling. At-least one will not further cause the damage. Also just by stopping further entangling, the rope automatically will start loosening as well, by it’s own weight. One of the core aims of one’s life as described in Hindu scriptures is to attain freedom(Mukti), the freedom from one’s own entanglement.

Out of 24 hrs of the day one is not sleeping at-least for 15 hrs. These 15 hrs his though process entangles him and it gets so tightly entangled sometimes that only way to stop further entangling is to sleep (stop the thought process). This is why people who needs more sleep are the ones who thinks too much unconsciously. Anther way to avoid this entangling is to have the thought process in your control i.e. conscious thinking.

If one decides to do an act daily, at specific time , then one brings certain consciousness in him that he becomes aware that he has to do something everyday. If he further decides to do specific list of actions then he is trying to be more conscious as he has list of things in his mind to do. If he further adds things such as chanting, reading, praying to his disciplined act then he is actually stopping his uncontrolled thoughts which are replaced by ones disciplined actions. It is true that it is not necessary to do actions related to God to loosen your entanglement, but it is observed that doing actions which brings positiveness in you are more impactful for achieving such freedom.

This is Pooja. Doing an positive/holy act regularly with full attention to disentangle from your own flow of unconscious thought process.

# Beyond Logic

We are living in a time where “logical mind” is given more value in terms or both money and respect, as these “logical minds” have helped to modify this world to enhance the luxuries of living.  I think it’s good to be logical but it’s not good to be bound to it or to protect the logical thinking to be highest form of thinking. If we do so we will miss the wonders of illogical things which are around us and could be the doors to future form of world.

With this in mind, I have my own illogical areas which bothers me all the time.

How small ?  In mathematics every real number can be divided into 2 halves. e.g. 10 can be split into 5 and 5. And then this 5 can further be split into 2.5 and 2.5 then then further 1.25 and 1.25 … so on. We use the mathematics to model the physical world. It has been used to so extent that people derived black hole’s deterministic behavior using math(I heard so). With this logical tool (math) can we think (just think) of splitting matter into halves. How far can we go ? Let’s say we reached to an atom. Now atom can be thought of made of 2 half atoms and each half then into 1/4 of atom. Every half part that we will come up here onward can be thought as made of 2 halves. That means everything is made up of infinite ( not sure what this word really means) smaller halves. Can our logic accept this ? Same thing is true if we go outwards.

Who does this ? When we are in deep sleep, what causes us to wake up when there are no external disturbances. e.g. when you are sleeping in a quiet room, and there are no disturbances of any kind to any of your senses (ear,touch,smell,taste),  you still wake up after certain time. What makes you wake up. Is the waker and the sleeping one the same ?

Light question?  We agree that everything that we could see is just a reflection of light from that thing into your eye(sensor). That also logically then makes sense that if we go in a very dark room(i.e. closed room not having any source of light)  then we can’t see anything as there is no light to reflect into your eyes. So it is clear that the light which is reflecting back from a thing must carry information about that thing to you. That means if we intercept this light at any point on the way, it must have the information about the thing it has visited.  Does this mean , any random light ray that we intercept actually has all the information about the things it has visited in the journey from the very beginning (source of light). So can we simply create a whole picture of this universe using simple ray of light ?

Infinity?
Everything beyond our limit of measurement we call it as Infinity. But we are not sure if it’s really Infinity. In fact do we know what infinity is? Is it just a word used to describe our limitations or it means something. In physical world how can something be infinite. Is Infinity in our experience? People say this universe is infinite but the moment they say word universe aren’t they thinking about their imagined finite thing? Anything which is in our senses we can say it’s logical, how can Infinity be logical ? Have we just taken this word granted and we are so unconscious about it that we just refer this word as taken granted. Isn’t it true about zero too. Is zero in our experience ? is it logical(really) ?  Could it be true that zero and infinity are same  and it’s just our logical mind not ready to accept ?

# Vipassana (विपश्यना)

Recently I attended 10 days vipassana course and hence this blog post. The contents of the post include my understanding of what vipassana (or Vipashyana) means , what is this ten day course about and my experience of staying this long without any contact with the outer world.

Vipassana is an ancient meditation technique used to eradicate impurities of your mind and find out root of any kind of misery you generate. Once you start practicing the technique, the path of happiness and peace in your life becomes very clear because you can just avoid the misery way on every occasion in your life. Importantly the technique teaches how to bring your mind under your control. Practicing the technique is the key. There is no time limit on when you can fully achieve the feat of bringing your mind fully under your control, but however far is the destination, it becomes closer if you step towards it. It may take a year , 5 years or entire life but as you practice you will definitely start seeing changes in yourself.

The base of the technique is  PRACTICE . Just knowing things at mental level won’t work. The understanding has to be done at body level / physical level. e.g. one knows anger is bad , but he/she becomes angry often and burns in anger for hours even after the incident , reason being he/she just knew “do not become angry” at mental level. Vipassana helps to change one’s behavior pattern by making him more conscious about himself. More you are conscious about yourself more peaceful you become.

Important observation you start to make by practicing vipassana is the root of any type of misery or pain lies with in you rather than outside object. e.g. Someone abuses you by saying some words. Now you become angry and start burning. You will notice that the intensity of this anger is more if the same person says same thing when your are along with your friends. Intensity is much more if the words has come from your own son. You will see that its the same word but all three situations has caused you different intensity of pain. Than means the pain generating factor is not the word, its the reaction you have generated. And you are sole responsible for your own reactions. You will start observing that more and more you are conscious, you gain control over your reactions. But as said before , knowing at mental level these concepts wont help at all. You must practice it. Vipassana is a technique of practicing of how to make one more conscious.

Apparently it’s the same technique used to achieve state of super consciousness. Gautama the Buddha has achieved that feat using it . He later introduced this technique to the world and many people got benefited out of it. But the purity of the technique got lost in last 2500yrs and if you practice wrong technique it wont benefit you and if it wont benefit oneself , one wont practice. This is how the technique got lost from world. Group of people from one country (Burma) kept it in it’s pure form from generation to generation. Visionary people of current time tried to spread this technique in it’s pure form back to entire world. And hence this 10 Days Course.

The 10 days course is all about learning how to practice Vipassana in it’s true nature. This course focuses on the practicing part of the technique rather than just mental understanding. To understand the true nature of the practice , nothing less than 10 days will work. One must fully undergo the rules of the course to get maximum understanding of the technique. The course is free of cost. Food and Stay for 10 days is free.  The course is available at various places in India and throughout the world. I attended the course from Igatpuri (the first centre in India, and is 50km from Nashik, Maharashtra). They accept donations at the end of the course(You get 125% tax exemption on the donation). The course reservation can be done at  https://www.dhamma.org

Rules of the course are very tough for one who is especially coming from internet world and has lot of addiction towards social n/w etc.Actually it’s tough for any addicted person. For the due course of 10 days, you won’t be having Mobile,Laptop, TV, Newspaper. You won’t talk (मौन) for 10 days. You will have only breakfast and Lunch (No dinner). You will be sitting by crossing your legs for 12 hrs of the day (you will have 10 mins breaks every 2 hrs). Basically you are completely isolated from happening world.

Your day starts at 4am in morning till 930pm, of which you will perform 10-11 hrs of meditation practice.  Vipashyana timings in day: 4.30am to 6.30am , 8 to 11am , 1 to 5 pm, 6 to 7pm, 8.30-9.15pm.  Other : Breakfast-6.30am , lunch- 11am , evening snaks and tea-5pm. Goenkaji’s Video discourse program : 7-8.30pm. This goes for 10 Days. Tenth day is Maitri divas. The schedule on this day has less hours of meditation and you can talk on this day.

There are ~ 15 group halls for meditation of varying seating capacity from 50 to 200. On day zero (arriving day) you will be assigned one meditation group hall and a permanent seat in that hall.  You will be given one residential room (shared/individual). Throughout the course you will go to your assigned meditation hall and be seated at assigned sit. You won’t talk with anyone other than your Acharya /Teacher for 9 days. On 10th day from 10am onwards , after Maitri teaching, you can talk with other colleagues (that too only in Canteen and residential quarters).  Absolute silence on main road (shanti pathar) of the campus throughout 10 days. Girls and boys have separate halls , canteen and residential quarters. Event if you come with your wife or colleague you wont meet that person for 9 days.  Course finishes on 11th day 6.30am in the morning, you will be served breakrfast on last day.

My experience at the Course.

I was practicing this technique (30 min /  day) since a year before joining this course. It benefited me a lot. I was having many questions regarding the course and so I attended this course.  So the experience shared below is effect of my past practice and the course as well.

First time I learned that sitting peaceful and ideal (doing absolutly nothing, not even moving your body parts ) for more than 2 hrs is the most difficult thing I have ever done. I am not kidding! So basically it was very tough course for me. At times I thought to run away. Every evening’s video discourse by Goenkaji is what kept me working for next day.  3rd and  5th day were absolutely tough.

At the end of 10th day I felt I have attended most difficult exam of my life. I felt there is less chaos in my mind than ever before. I felt very fresh and energetic. But I knew this wont last long.  My mind has a behavior pattern to cause misery over the time and so I must practice on daily basis to get real benefit out of it. I wished  I should have got introduced to this technique earlier in my life (in my twenties).  But nevertheless, I got it is what more important for me. I felt thankful to S N Goenka who explains the technique in unique manner and generates belief towards the technique.Once someone has little hope or shradhha towards something ,he tries. The technique is so powerful that if you practice it , it will start giving you fruits of happiness in life. And once you start getting fruits , you will strongly practice it. Same thing started happening to me. Ans so I am thankful for my entire life to S N Goenka. At the same time started feeling greatness towards Gautama, the super human who found the technique.

Purifying ones mind is long process. The long journey becomes shorter only if we step towards it. Importantly the path must be correct. I feel I have found right path , now walking on the path is what remains.

Mangal Ho (be happy)!

Nature is a place of great secrets. These are secrets until we unlock them. Surprisingly every time we unlock one , we end up with many more secrets inside. To unlock such secrets we need  be able to find the link between various things.  To me everything in the universe is linked in one form or other.  This blog post is about various links that I see and I feel worth to be looked upon.

The air we breath is produced by trees. Why would I totally depend on something created by trees. Could there be a link between oxygen creators and oxygen absorbents ?  There are many different types air molecules , but why only oxygen ,produced by trees ,is our dying need. Is it that there was large amount of oxygen prior to animals on this earth , and we could survive only if oxygen’s abundance is reduced ?  Have we evolved ourselves to breath oxygen in a way to maintain some kind of balance in nature with trees.The molecule created via photosynthesis inside a leaf becomes a necessary element in chemical reaction inside human body to release energy from sugar molecules. I would call this as Energy Link

Human senses are capable of detecting only those changes which takes more than 0.1 second. e.g. if you are given an needle injection shot in less than 0.1 second, then you wont know if it was given at all. We can say that processing speed factor of senses is 0.1 second.  Earth takes 86400 seconds to rotate around itself to cause day and night. Because it is much much larger than 0.1 second (~10^6  times) we can detect the presence of day and night. If Day and night would have been faster than 0.1 second , we could never have been able to observe it.  The question is , is it just a coincidence or there is link between our consciousness factor and speed of earth rotation ?  May be we have developed our processing speed during evolution to be much faster than day-night cycle speed. This also gives another thought , are there such things happening around us which are way faster than our detection and so we are missing it?   I would call this as a Time Link.

Everyone who has ever lived on this earth died one day or will die. We have not yet evolved ourselves to be able to live forever. This is one of the pure truths of life. We are mortals. Rather, every living being is mortal. However we become rich, powerful, peaceful, intelligent we can not escape the death cycle. “Even Einstein dies” is the very truth we experience. Now if “being born” and “dying” are linked via life , why not  “dying” and “getting birth” are linked ? They can be linked based on state of mind at the time of death. More stable you are at the time of death, more peaceful your nature will be in the next life. If you die absolutely peaceful like Buddha, you need not another life at all.  The link between death and rebirth can be called as  Life link.

There are many more links like these and is just a step into knowing the nature of the world we live in.  Share your thoughts on these lines if you are thinking on similar lines in the comments below.

# Shiv (शिव)

This post is about my understanding of Shiv (as in lord Shiva or lord Shankar). All of my thoughts below are inspired from Mr. S N Goenka (famously known as Vipashyana guru).

Meaning of Shiv word itself is “well being” , “happy being” , “being in peaceful state” , “being in pure state”. One of the very intelligent ideas of Hinduism is to represent most aspired and most required state for human beings in a form of God. Being in peaceful state ,no matter what happens , is most difficult and most wished state to reach in this one life time.

Hrishi’s and saints found that attaining peace of mind is most important and at the same time a very tough process. They thought of representing this peaceful state in a form of God so that this becomes inspiration to normal people and looking at such peaceful God they may try to inherit the similar state in their life. And so is this Lord Shiva.

Ancient philosophers were very thoughtful and to represent this God of peace they thought of moon being on his head. Moon light is cool light (unlike sun) and logically someone can think moon as cool piece. Shiva has moon on his head , it means his head , his mind is as cool as moon. Coolness is infact peacefulness.

Shiva has river Ganga flowing from his head. Water of Ganga is very cold at it’s source and down the river too. Shiva’s mind is utmost cold that it can be thought as his head is source of such cold river.

Shiva has dangerous animal snake around his neack. Snake is also called as death as just a single bite of it can cause death of any other animal. Such of this animal even cannot affect Shiv’s peace. In the scariest of such situations Shiv can stay calm and peaceful.

Shiva’s body is blue. He has been pictured as person who drank deadliest poison resulted from sagar manthan. Poison is one of the hottest natured substance and can vanish a life in no time if consumed. Shiva is imagined to have drunk this huge poison and still his peace of mind is unaffected. He is such a cold natured Hrishi.

Ancient philosophers has done a great deal of imagination to have thought of this coolest image to inspire peaceful living in generations.

To me worshipping Shiva is taking time in your life to imagine such concept who is cool like moon, whose head is as cool as source of Ganga, whose peace is untouched by deadliest animal, whose body remains in cold form even he drinks poison. And try to inherit some of this in my life to make best use of being human.

We spend enough energy fighting if shiva exist or not , if Ganga starts from his head or not and blind believers always fail to spread actual message of Shiv to scientific , logical thinkers.

We are all thankful to such philosophers of old era to have inspired us to live a life in such peaceful way or Shiva way. It’s our duty to carry such messages for future generations.

Thanks for taking time in your busy life to visit Purity. I hope you have a different thought to take with you today.

# Nothing!

There has been lot of discussion in recent decades about “state of nothingness”. Philosophers , scientists , teachers , scholars and many other groups have been discussing about was there “nothing” before this universe.  Most of the discussions goes on understanding of nothing itself .Can there exists absolute nothing or what is nothing itself is yet to be locked into scientific discoveries.

This blog post is inspired from Lawrence Krauss‘s discussions and thinking about  nothing.  This blog post is not about theoretical physics etc and is all about my honest opinion and  my thoughts on “nothingness“.

Lets start with very simple state of nothing , and for that I put a statement : “There is nothing in my pocket.” This is very relative statement and for me it means there is absence of things which are commonly kept and looked upon in the pocket. But there exists air inside , so definitely there is not nothing because air is something. As long as we find something we can not say it’s nothing.

Lets create vacuum in a iron cubical box by removing air. Now can you say there is nothing in the box ?   Electromagnetic waves can travel trough vacuum and on earth we have so many electromagnetic things going on (mobile , radio , television signals and what not are all electromagnetic)  and so there exists something in the box. Also because we can’t realistically make 100% vacuum so there will always be something in out iron cubical box on earth.

Now let’s go to deep space and imagine 1m cubical area out there. Again assume vacuum is out there. Is there nothing ?  What about light from stars, you will always have some light (low/high intensity) out there coming from some or other star.

We can go further deeper and we will see Gravity,Time, Magnetic force etc out there.  Also we can call space itself a something. Now if space itself is something then it’s highly difficult to imagine things which can exists without space. Only your thoughts then can exists without taking space(and even someone can say thoughts take space in brain).

It seems to be inconclusive or branching discussion and so it will be good to first arrive at a point or definition of few important things out here and then again talk if “nothing” can exists.

Two of such things are “exists” and “a thing”. What are all things that we can say they fit into category of  “a thing”. What is the criteria on which we can call if it “exists” ?

So in conclusion , to find out if  “nothing exists” we need to know what do we actually mean by “something exists”?  If we answer second question we may be able to categories  what is “nothing”  and if it exists or not.

Please watch this space for further discussion on this topic on my blogpost.

Thanks for your valuable time to visit Purity.  I hope you had a different thought to take with you today.

# Time-2

This “Time” series is my honest attempt to know what do we mean by “Time”. What is the nature of it. It is offcourse not necessary ( and is not ) to match with what someone says.  Ans so I am saying it as my honest attempt.

In previous blog (link) we discussed if Time is purely just a discovery by humans, i.e. have we discovered it ? To be able to discover something we need source for that thing , medium by which it travels (or stays) and our senses to detect it. For time we don’t have any of those. There is no source that creates time, time does not have medium , and we don’t have any sensor which can detect time.

We discussed that we have memories of something happened to us and our consciousness tells that we have memory. e.g. we were very little conscious when we were a year old. We don’t recall any of the things happened to us at that time. We individual can not surely tell if we were one year old for sure in past (we logically think that to become 30 yrs old we must have been 1 year old and that’s it. There is no real proof that one himself can generate that he was one year old.  Your parent can show you old photos ,videos etc but it’s not you , it’s them.)

So consciousness is helpful to let one confidently differentiate between past and present.

Let’s go to other branch to see if Time is our invention.

Invention is something lies in our creation category. e.g. GOD is our invention. We have not discovered GOD , instead we have created it for our own sake.

Is Time like a GOD , that we created for own sake ? Both of them does not have source of creation , and we either don’t have any sensor to detect it’s presence.

Whether or not GOD is an invention is very debatable and so let’s not fit time into invention category just because my personal opinion about GOD being an invention. Another example of invention would be let’s say a Chair. It’s an instrument to sit and take rest(it’s a physical instrument). Another example would be mathematics. It is our invention (virtual). It is a thought or collection of various logical thoughts.

Is Time just a thought or is it a external independent thing ? We will discuss more in upcoming blogs.

Thanks for taking time to visit Purity from your busy life. I hope you had a different thought today.
