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.
The Atman alone is eternal. Hospitals will tumble down. Railroad givers will all die. This earth will be blown to pieces, suns wiped out. The Atman endures for ever.
-Swami Vivekananda
