If the soul is infinite and exists everywhere, as it must do, if it is a spirit, what is meant by its taking up bodies and passing through body after body? The idea is that the soul neither comes nor goes, neither is born nor dies. How can the omnipresent be born? It is meaningless nonsense to say that the soul lives in a body. How can the unlimited live in a limited space? But as a man having a book in his hands reads one page and turns it over, goes to the next page, reads that, turns it over, and so on, yet it is the book that is being turned over, the pages that are revolving, and not he — he is where he is always — even so with regard to the soul. The whole of nature is that book which the soul is reading.
Each life, as it were, is one page of that book; and that read, it is turned over, and so on and on, until the whole of the book is finished, and that soul becomes perfect, having got all the experiences of nature. Yet at the same time it never moved, nor came, nor went; it was only gathering experiences. But it appears to us that we are moving. The earth is moving, yet we think that the sun is moving instead of the earth, which we know to be a mistake, a delusion of the senses. So is also this, delusion that we are born and that we die, that we come or that we go. We neither come nor go, nor have we been born. For where is the soul to go? There is no place for it to go. Where is it not already?
(VI, 23 – 24)
Swamiji visualises nature as a great book with infinite number of pages and the reader as the human soul skipping through the pages. Life and death are just two pages, nothing else. Here one can recall Sri Krishna’s observation in Gita, bodies are like old clothes to be used and discarded. (Bhagavat Gita II.)
