"All logic was left behind, all rationality was left behind. You cannot dictate to existence, because it does not follow your logic. Logic is man-made.

"There was a point in Albert Einstein's life when he remembers that he was wavering about whether to insist on being rationalbut that would be foolish. It would be human, but not intelligent. Even if you insist on logic, on rationality, existence is not going to change according to your logic; your logic has to change according to existence. And the deeper you go, existence becomes more and more mysterious.

"A point comes when you have to leave logic and rationality and just listen to nature. I call it the ultimate understanding – but not in the ordinary sense of understanding. You know it, you feel it, but there is no way to say it.

"Man is a mystery, woman is a mystery, everything that exists is a mystery – and all our efforts to figure it out are going to fail.

"I am reminded of a man who was purchasing in a toy shop a present for his son for Christmas. He was a well-known mathematician, so naturally the shopkeeper brought out a jigsaw puzzle. The mathematician triedit was a beautiful puzzle. He tried and tried and tried and started perspiring. It was becoming awkward: the customers and the salesmen and the shopkeeper were all watching and he has not been able to bring the puzzle to a solution.

"Finally he dropped the idea and he shouted at the shopkeeper: 'I am a mathematician and if I cannot solve this jigsaw puzzle, how do you think my small boy will be able to?'

"The shopkeeper said, 'You don't understand. It is made in such a way that nobody can solve it – mathematician or no mathematician.'

"The mathematician asked, 'But why is it made in this way?'

"The shopkeeper said, 'It is made in this way so that the boy from the very beginning starts learning that life cannot be solved, cannot be understood.'

"You can live it, you can rejoice in it, you can become one with the mystery, but the idea of understanding as an observer is not at all possible."
