Notes of a series of inspiring class talks of Swami Vivekananda delivered during his seven weeks' stay at Thousand Island park, U.S.A. on various religious and philosophical topics and recorded by Miss S. E. Waldo, an American disciple.
What is material and what is not material? When the world is the end and God the means to attain that end, then that is material. When God is the end and the world is only the means to attain that end, spirituality has begun.
-Swami Vivekananda
