Eddington, in 1930, said that we were in search of matter, but now all new insight into matter shows that there is no matter, it looks more and more like a thought and less and less like a thing. Suddenly the insight of Buddha became very, very significant again, because Buddha did the same with human matter, the human stuff. Physicists were trying to penetrate matter in an objective way to find out what was there inside it, and they found nothing. Total emptiness. And the same was discovered by Buddha in his inner journey.
