It comes from man's limitations. And there he saw that no matter what you give him -- wealth, power, position, all manner of pleasure and happiness -- still man will remain in pain, in trouble; still he will have sorrow. If there is a way of coming out of it, it is only one way, and that way is the way of perfection. Therefore, instead of finding thousands of ways of helping humanity, he stuck to one way: to help man towards spiritual perfection, to help man find his power, his inspiration, his happiness, his peace, not outside, but within himself.
