This is a powerful lecture delivered by Swami Vivekananda in San Francisco in 1900.It is one of the best books delineating, in brief, the fundamentals of Vedanta in a lucid, authoritative and candid tone.
What I want is muscles of iron and nerves of steel, inside which dwells a mind of the same material as that of which the thunderbolt is made.
-Swami Vivekananda
