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.
This I have seen in life -- those who are overcautious about themselves fall into dangers at every step; those who are afraid of losing honor and respect, get only disgrace; and those who are always afraid of loss, always lose.
-Swami Vivekananda
