"But it was a fact. Not even half a dozen persons existed with whom Einstein could talk easily – because Einstein had reached to such peaks in mathematics that they could not be communicated in ordinary mathematical symbols.

"Even if Einstein tries to convey his knowledge, you will hear it but not understand it – because just 'hearing' is not understanding. And when you do not understand it, there is every possibility you will misunderstand it – because in understanding and non-understanding there is an in-between phenomenon: that of misunderstanding. No one is ready to accept that he has not understood. So when there is no understanding, it does not mean 'no understanding.' In ninety-nine cases out of a hundred, it means 'misunderstanding' – because no one is ready to say that he does not understand. Everyone will say that he understands – and then misunderstanding follows.

"So, if in mathematics, which is not an esoteric knowledge…in mathematics, which is not concerned with the ineffable…. If in this twentieth-century world in which mathematics has existed for five thousand years continuously…. Thousands and thousands of minds are trained in mathematics: every university all over the world teaches it, every primary school teaches it. With so much training, so much knowledge, so many departments in so many universities teaching it, and Einstein says: 'Only six persons exist to whom I can communicate what I know.' Then you can understand the difficulty of communicating spiritual experience.

"An esoteric group means a group which is specially trained for a particular master – because the phenomenon is rare. A Buddha happens after thousands of years. And when there is a happening like Buddha, how will he be able to communicate? Buddha will be there, the world will be there – but of no meaning. Buddha cannot communicate directly, so an esoteric group – an inner group – is trained. The training is so that this group can become a mediator between Buddha and the world. A special group is specially trained to understand Buddha and to interpret Buddha to the world – because between a Buddha and the world there is such a gap that Buddha will not be understood at all."
