Swami Vivekananda's illuminative ideas on religion are spread over nearly 4200 pages of his Complete Works. This book containing eight lectures is a compilation from the same and serves as a small introduction to his voluminous writings, talks, and lectures on the subject.
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
