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.
When we can attach the mind to -- or detach it from -- the sense at our will, we shall really possess character. Then alone we shall have taken a long step towards freedom; before that, we are mere machines.
-Swami Vivekananda
