You cannot exhaust the unknowable. The unknown will become known, then the known may become again unknown. It has happened many times. Many things have been known and then they became unknown because the society became uninterested in them. Many times it has happened. If you go back and ask people who work deeply into the past, they say almost all that we know has been known some time before and then it was forgotten.
Columbus was not the first man who discovered America; many people before him discovered it, and then America was lost again. In Mahabharata, one of the oldest Indian scriptures – at least five thousand years old, more is possible – there is mention of Mexico: Arjuna had many wives, one wife was a Mexican. In many other scriptures of the world America is mentioned. Columbus was not the first to discover it – he rediscovered it. There is mention of airplanes in many scriptures of the world; this is not the first time that we have discovered the airplane. We discovered it and we became uninterested in it; it was lost. I have not come to know anything that has been discovered for the first time. Everything has been discovered and lost. It depends on the society: if the society takes an interest, it is okay; otherwise it is lost.
The known will become unknown, the unknown will become known. But there is a third dimension: the unknowable. Science doesn’t believe in the unknowable. She says, “The unknowable is nothing but the unknown.” And religion says it is a totally different dimension: that which will always remain unknown – because its intrinsic nature is such that the mind cannot cope with it. The vast, the infinite, the endless, the beginningless, the total – the total cannot be comprehended in any way by the part, because how can the part comprehend the total? How can the mind comprehend that from which the mind arises? How can the mind know that to which the mind goes back? It is impossible! It is simply impossible. How can we know that from which we come? We are just like waves – how can a wave comprehend the whole ocean? It can claim, because the ocean never refutes anything – it simply laughs. It is just like a child claiming something before the parents, and they laugh.
The incomprehensible is there – the unknowable is there.
You could not discover the limits of the soul
even if you traveled every road to do so –
such is the depth of its meaning.
How can you know yourself? Every religion says: “Know thyself!” But how can you really know yourself? Then who will be the knower and who will be the known? – because knowledge depends on a division. I can know you, you can know me, because I become an object and you become the knower – but how can you know yourself? And if you try to know, that which you will know will not be yourself. The knower will always recede; the knowledge will always be bracketed as an object and you will be bracketed as a subject.
