Unknowable
These three words have to be remembered: the known, the knowable and the unknowable.
The known was unknown yesterday. The knowable is unknown today but tomorrow it may become knowable, known. Science believes in only two categories, the known and the unknown. But the unknown means the knowable; up to now we have not been able to know it but sooner or later we will know it. Hence science believes a moment will come in history, some time in the future, where there will be nothing left to know, when the whole unknown will have become known. But religion has a third category also, the unknowable, which always remains unknowable. It was unknowable yesterday, it is unknowable today, it will remain unknowable tomorrow.
Science thinks that existence can be demystified, religion knows it cannot be demystified because that unknowable will always remain a mystery. And that unknowable is called god, truth, nirvana -- so many names have been given to it -- tao, dhamma, logos, but one quality is definitely there in all these words: it is unknowable, it is an absolute mystery. You can enter into it, you can become part of it but you cannot know it.
You can live it but you cannot know it, you can taste it but you cannot say anything about it, You can feel it in your belly but you will be absolutely dumb. And that is the most precious experience. It is experienceable but not expressible. That's why it cannot become part of the known.
Many people have experienced it -- Buddha experienced it, Lao Tzu experienced it, Patanjali experienced it, Kabir experienced it, but nobody has ever been able to say anything about it. All that they say is how to find it, but they never say anything about that which you are going to find.
Lao Tzu begins his book, TAO TE CHING: 'Truth is that which cannot be expressed. Remember this,' he says 'and then you can read my book. Don't forget it -- because truth you will not find in the words. Perhaps one can find it in the gaps between the words or between the lines but not in the words, not in the lines themselves.'
That is our search -- the unknowable. And the only way to seek it is to dissolve into the whole just like a dewdrop dissolves into the ocean and becomes it.
