You ask me: “What is the most fundamental error of all these religions?” There are many errors and they are all fundamental, but first I would like to talk about the most fundamental. The most fundamental error of all the religions is that none of them was courageous enough to accept that there are things which we don’t know. They all pretended to know everything, they all pretended to know all: they were all omniscient.
Why did this happen? It was because if you accept that you are ignorant about something then doubt arises in the minds of your followers. If you are ignorant about something, who knows? – you may be ignorant about other things also. What is the guarantee? To make it foolproof, they have all pretended, without exception, that they are omniscient.
The most beautiful thing about science is it does not pretend to be omniscient. Science does not pretend to be omniscient; it accepts its human limits. It knows how much it knows, and it knows that there is much more to know. And the greatest scientists know of something even deeper. The known they know, the boundaries of the knowable they will know sooner or later – they are on the way. And the unknowable: only the greatest scientists like Albert Einstein will be aware of the third category, the unknowable, which will never be known. Nothing can be done about it because the ultimate mystery cannot be reduced to knowledge.
We are part of existence – how can we know existence’s ultimate mystery?
We have come very late; there was nobody present as an eyewitness. And there is no way for us to separate ourselves completely from existence and become just an observer. We live, we breathe, we exist with existence – we cannot separate ourselves from it. The moment we are separate, we are dead. And without being separate, just a watcher, with no involvement, with no attachment, you cannot know the ultimate mystery; hence it is impossible. There will remain something always unknowable. Yes, it can be felt, but it cannot be known. Perhaps it can be experienced in different ways, not like knowledge.
You fall in love – can you say you know love? It seems to be a totally different phenomenon. You feel it. If you try to know it, perhaps it will evaporate in your hands. You cannot reduce it to knowing. You cannot make it an object of knowledge because it is not a mind phenomenon. It is something to do with your heart. Yes, your heartbeats know it, but that is a totally different kind of knowledge; the intellect is incapable of approaching the heartbeats.
But there is something more than heart in you: your being, your life source. Just as you know through the mind, which is the most superficial part of your individuality, you know something from your heart, which is deeper than the mind. The mind cannot go into it; it is too deep for it. But behind the heart, still deeper, is your being, your very life source. That life source also has a way of knowing.
When mind knows, we call it knowledge. When heart knows, we call it love. And when being knows, we call it meditation.
