On this page we reproduce the account of the experience which appears in the biography by Narasimha Swami.
"So, on that day as I sat alone there was nothing wrong with my health. But a sudden and umistakeable fear of death seized me. I felt I was going to die. Why I should have so felt cannot be explained by anything felt in my body. Nor could I explain it to myself then. I did not however trouble myself to discover if the fear was well grounded. I felt 'I was going to die,' and at once set about thinking what I should do. I did not care to consult doctors or elders or even friends. I felt I had to solve the problem myself then and there.
"The shock or fear of death made me at once introspective, or 'introverted'. I said to myself mentally, i.e., without uttering the words — 'Now, death has come. What does it mean? What is it that is dying? This body dies.' I at once dramatized the scene of death. I extended my limbs and held them rigid as though rigor-mortis had set in. I imitated a corpse to lend an air of reality to my further investigation, I held my breath and kept my mouth closed, pressing the lips tightly together so that no sound might escape. Let not the word 'I' or any other word be uttered! 'Well then,' said I to myself, 'this body is dead. It will be carried stiff to the burning ground and there burnt and reduced to ashes. But with the death of this body, am "I" dead? Is the body "I"? The body is silent and inert. But I feel the full force of my personality and even the sound "I" within myself, — apart from the body. So "I" am a spirit, a thing transcending the body. The material body dies, but the spirit transcending it cannot be touched by death. I am therefore the deathless spirit.' All this was not a mere intellectual process, but flashed before me vividly as living truth, something which I perceived immediately, without any argument almost. 'I' was something very real, the only real thing in that state, and all the conscious activity that was connected with my body was centred on that. The 'I' or my 'self' was holding the focus of attention by a powerful fascination from that time forwards. Fear of death had vanished at once and forever. Absorption in the self has continued from that moment right up to this time. Other thoughts may come and go like the various notes of a musician, but the 'I' continues like the basic or fundamental sruti note which accompanies and blends with all other notes."
