" Although a man has not studied a single system of philosophy, although he does not believe in any God, and never has believed, although he has not prayed even once in his whole life, if the simple power of good actions has brought him to that state where he is ready to give up his life and all else for others, he has arrived at the same point to which the religious man will come through his prayers and the philosopher through his knowledge; and so you may find that the philosopher, the worker, and the devotee, all meet at one point, that one point being self-abnegation. "
