I profit from a philosopher only insofar as he can be an example. That he is capable of drawing whole nations after him through this example is beyond doubt; the history of India, which is almost the history of Indian philosophy, proves it. But this example must be supplied by his outward life and not merely in his books — in the way, that is, in which the philosophers of Greece taught, through their bearing, what they wore and ate, and their morals, rather than by what they said, let alone what they wrote.
