I remember, someone related an anecdote to me. He was a great searcher, and he told me this about his professor who taught him for five years in a medical college. The professor was a great scholar of his subject. The last thing he did was to gather his students and tell them, “One thing more I have to teach you. Whatsoever I have taught you is only fifty percent correct, and the remaining fifty percent is absolutely wrong. But the trouble, is, I don’t know which fifty percent is correct and which fifty percent is incorrect – I don’t know.”

The whole edifice of knowledge is such. Nothing is certain, no one knows, everyone is groping. Through groping we create systems, and there are thousands and thousands of systems. Hindus say something, Christians say something else, Mohammedans still something else – all contradictory, all contradicting each other; no agreement, no certainty – and all these sources are the sources for your mind. You collect: your mind becomes a junk-yard; confusion is bound to be there. Only a person who doesn’t know much can be certain. The more you know, the more uncertain you will become.

People, primitive people, were more certain and apparently appeared to be more clear. There was no clarity – simply unawareness of facts which could contradict them. If the modern mind is more confused, the reason is that the modern knows more. If you know more you will be more confused, because now you have more knowledge, and the more you know, the more uncertain you become. Only idiots can be certain, only idiots can be dogmatic, only idiots will never hesitate. The more you know, the more the earth is taken away from your feet, the more hesitant you become. What I mean to say is, the more the mind grows, the more you will know the nature of the mind is confusion.

When I say only idiots can be certain, I don’t mean that a master is an idiot – because he is not uncertain. Remember the difference. He is not certain, he is not uncertain – he is simply clear. With the mind, uncertainty; with the idiotic mind, certainty. With no mind both disappear – certainty and uncertainty.

Buddha is a clarity, a space, open space. He is not certain – there is nothing to be certain. He is not uncertain, because there is nothing to be uncertain. Only one who is seeking certainty can be uncertain. Mind is always uncertain and always seeking certainty; always confused and always seeking clarity. A master is one who has dropped the mind; and with the mind all confusion, all certainty, all uncertainty, everything is dropped.

Look at it in this way: your consciousness is just like the sky and your mind is just like the clouds. The sky remains untouched by the clouds. They come and go; no scar is left behind. The sky remains virgin: no record, no footprints, nothing of the clouds, no memory. They come and they go; the sky remains undisturbed. This is the case within you also: the consciousness remains undisturbed. Thoughts come and go, minds evolve and disappear. And don’t think that you have one mind; you have many minds, it is a crowd. Your minds go on changing.
