The meaning of the living words that come out of the experiences of great hearts can never be exhausted by any one system of logical interpretation. They have to be endlessly explained by the commentaries of individual lives, and they gain an added mystery in each new revelation. To me the verses of the Upanishads and the teachings of Buddha have ever been things of the spirit, and therefore endowed with boundless vital growth; and I have used them, both in my own life and in my preaching, as being instinct with individual meaning for me, as for others, and awaiting for their confirmation, my own special testimony, which must have its value because of its individuality.
