In this search some people think that one can perhaps find out from science or from art something which is behind this manifestation; and surely, whether the quest be material or spiritual, in the end one will arrive, and one must arrive, at that goal which is the same for everyone. Scientists and engineers, people who are absorbed in research into material things and hardly ever think of spiritual matters, even they, after much research, arrive very close to the same knowledge which is the ultimate knowledge. Therefore, whatever a man may seem to us, materialist, atheist, or agnostic, we cannot really call him that, because in the end his goal is the same and his attainment is the same. If he really reaches the depths of knowledge, if he goes far enough, whatever he was searching for he will arrive at the same goal.
