Here is the description of calamity that occurred to UG Krishnamurti in his own words. This excerpt is taken from his book which is without any claim for copyrights.

Then began the changes — from the next day onwards, for seven days — every day one change. First I discovered the softness of the skin, the blinking of the eyes stopped, and then changes in taste, smell and hearing — these five changes I noticed. Maybe they were there even before, and I only noticed them for the first time.
(On the first day) I noticed that my skin was soft like silk and had a peculiar kind of glow, a golden color. I was shaving, and each time I tried to shave, the razor slipped. I changed blades, but it was no use. I touched my face. My sense of touch was different, you see, also the way I held the razor. Especially my skin — my skin was soft as silk and had this golden glow. I didn’t relate this to anything at all; I just observed it.

(On the second day) I became aware for the first time that my mind was in what I call a ‘declutched state’. I was upstairs in the kitchen and Valentine had prepared tomato
soup. I looked at it, and I didn’t know what it was. She told me it was tomato soup, and I tasted it, and I recognized “This is how tomato soup tastes.” Then I swallowed the soup, and then I returned to this odd frame of mind — though ‘frame of mind’ is not the word for it; it was a frame of ‘not mind’ — in which I forgot again. I asked again “What is that?” Again she said it was tomato soup. Again I tasted it. Again I swallowed and forgot. I played with this for some time. It was such a funny business for me then, this ‘declutched state’; now it has become normal. I no longer spend time in reverie, worry, conceptualization and the other kinds of thinking that most people do when they’re alone. My mind is only engaged when it’s needed, for instance when you ask questions, or when I have to fix the tape-recorder or something like that. The rest of the time my mind is in the ‘declutched state’. Of course now I have my memory back — I lost it at first, but now I have it back — but my memory is in the background and only comes into play when it’s needed, automatically. When it’s not needed, there is no mind here, there is no thought, there is only life.

(On the fourth day) something happened to the eyes. We were sitting in the ‘Rialto’ restaurant, and I became aware of a tremendous sort of ‘vistavision’, like a concave mirror. Things coming towards me, moved into me, as it were; and things going away from me, seemed to move from inside me. It was such a puzzle to me — it was as if my eyes were a gigantic camera, changing focus without my doing anything. Now I am used to the puzzle. Nowadays that is how I see. When you drive me around in your Mini, I am like a cameraman dollying along, and the cars in the other direction go into me, and the cars that pass us come out of me, and when my eyes fix on something they fix on it with total attention, like a camera. Another thing about my eyes: when we came back from the restaurant I came home and looked in the mirror to see what was odd about my eyes, to see how they were ‘fixed’. I looked in the mirror for a long time, and then I observed that my eyelids were not blinking. For half an hour or forty-five minutes I looked into the mirror — still no blinking of the eyes. Instinctive blinking was over for me, and it still is.

(On the fifth day) I noticed a change in hearing. When I heard the barking of a dog, the barking originated inside me. And the same with the mooing of the cow, the whistle of the train — suddenly all sounds originated inside me, as it were – coming from within, and not from outside — they still do.
Five senses changed in five days, and on the sixth day I was lying down on a sofa — Valentine was there in the kitchen — and suddenly my body disappeared. There was
no body there. I looked at my hand. (Crazy thing — you would certainly put me in the mental hospital.) I looked at it — “Is this my hand?” There was no questioning here, but the whole situation was like that – that is all I am describing. So I touched this body — nothing — I didn’t feel there was anything there except the touch, you see, the point of contact. Then I called Valentine: “Do you see my body on this sofa? Nothing inside of me says that this is my body.” She touched it — “This is your body.” And yet that assurance didn’t give me any comfort or satisfaction — “What is this funny business? My body is missing.” My body had gone away, and it has never come back. The points of contact are all that is there for the body — nothing else is there for me — because the seeing is altogether independent of the sense of touch here. So it is not possible for me to create a complete image of my body even, because where there’s no sense of touch there are missing points here in the consciousness.
On the seventh day I was again lying on the same sofa, relaxing, enjoying the ‘declutched state’. Valentine would come in, I would recognize her as Valentine; she would go out of the room — finish, blank, no Valentine — “What is this? I can’t even imagine what Valentine looks like.” I would listen to the sounds coming from inside me?” I could not relate. I had discovered that all my senses were without any coordinating thing inside: the co- ordinator was missing.
I felt something happening inside of me: the life energy drawing to a focal point from different parts of my body. I said to myself “Now you have come to the end of your life. You are going to die.” Then I called Valentine and said “I am going to die, Valentine, and you will have to do something with this body. Hand it over to the doctors — maybe they will use it. I don’t believe in burning or burial or any of those things. In your own interest you have to dispose of this body — one day it will stink — so, why not give it away?” She said “You are a foreigner. The Swiss government won’t take your body. Forget about it,” then she went away. And then this whole business of the frightening movement of the life force coming to a point, as it were. I was lying down on the sofa. Her bed was empty, so I moved over to that bed and stretched myself, getting ready. She ignored me and went away. She said “One day you say this thing has changed, another day this thing has changed, a third day this thing has changed. What is this whole business?” She was not interested in any of those things — never was she interested in any of these religious matters — never heard of those things. “You say you are going to die. You are not going to die. You are all right, hale and healthy.” She went away. Then I stretched myself, and this was going on and on and on. The whole life energy was moving to some focal point — where it was, I don’t know. Then a point arrived where the whole thing looked as if the aperture of a camera was trying to close itself. (It is the only simile that I can think of. The way I am describing this is quite different from the way things happened at that time, because there was nobody there thinking in such terms. All this was part of my experience, otherwise I wouldn’t be able to talk about it.) So, the aperture was trying to close itself, and something was there trying to keep it open. Then after a while there was no will to do anything, not even to prevent the aperture closing itself. Suddenly, as it were, it closed. I don’t know what happened after that.

This process lasted for forty-nine minutes — this process of dying. It was like a physical death, you see. Even now it happens to me: the hands and feet become so cold, the body becomes stiff, the heartbeat slows down, the breathing slows down, and then there is a gasping for breath. Up to a point you are there, you breathe your last breath, as it were, and then you are finished. What happens after that, nobody knows.
When I came out of that, somebody said there was a telephone call for me. I came out and went downstairs to answer it. I was in a daze. I didn’t know what had happened. It was a physical death. What brought me back to life, I don’t know. How long it lasted, I don’t know. I can’t say anything about that, because the experiencer was finished: there was nobody to experience that death at all…. So, that was the end of it. I got up.

Between the period of 1900-2000 saw a major outburst of technological advances, demolishing of religious establishment and stranglehold, development of scientific thinking, two disastrous wars of world. There were peoples who made fortune and became billionaire from beggar. After all those good or bad but overwhelming changes and peoples obsessed towards things suddenly realization started in the middle of century that where we are going and what is the essence of all these? Peoples started asking question to themselves and others and started rejecting well established foundation of value system built on ages.

You will see that last century whole of media like newspapers, movies, writing and artifacts were flooded with scientific ideas, fantasies about time machine. Peoples in a closed room discussing the future of mankind, woman’s equality movement and their participation in mainstream economy, human values and morality, superstitions of religions, accumulating knowledge of society and its damage on individuals all those romantic things. Talks and fictions written on machines taking over the world one day. Where are all of topics gone today?

One thing is obvious that peoples are busy with earning their livelihood in one other or other organized institutions like today’s corporate biggies houses lots of workers and their time is spent staring computers. There is little time left afterward for individuals and their are obsessed with watching movie show, spent hours in health clubs or do some sport activities. Its not that peoples have become complete robotic rather their goals, wantings, fantasies and dreaming all are re-framed in today’s new and commercial world. Peoples are more conscious on their appearance and how they talk, walk and look.

Peoples telling through advertisement that how you should look by using their beauty creams, models to imitate before us in cinema that this is how we should become. We had spiritual models they are replaced by actors, singers and rich peoples. Sex is gaining commercial values more and more peoples fantasies about love and sex through build up from cinemas whereas the actual sex is remained restraint.

From the title it might not be clear what I am going to tell in this post, but I would like to discuss on the matter of how we experience things and make their generalization. Any generalization is supposed to be applied in cases which is in our criteria well fitter to be explained by that theory and we immediately say something based on previous experience we always try to explain new happenings of things.

Take the case of liking and disliking different variety of foods, it could be based on adolescence habits we might reject different cuisine or based on hygiene or out notion of effort put into preparing certain kind of meal. Some people will from their family tradition learn about different ingredient which might not be well suited for the stomach for example wheat flour are used to make variety of eatable items in home and sometimes maida flour are also being used in making stuffs like noodle. Now thing would be clear that a person who is habitual of eating food made of certain ingredient for a long time their body wouldn’t adopt a new content immediately. So if you first time eater of maida made consumable’s might show some or other forms of sign that body did not take it easily. Now here comes our role that we try to relate this observation with our day to day activity then make an ideation out of it. This ideation will then become fortified each time after encounter with same situation and you explain it through past knowledge.

Above ideation is passed through generations for example a kid is constantly told by parents that avoid certain things to eat or do whatever be the case. In cases of sickness they are again explained by parents with their past knowledge what caused it. Now upon deeply seeped ideas into consciousness will always bring about the same abnormal bodily behavior, otherwise body would have started adopting into new conditions which it is forced by the fact that no other option is available.
