This is the first Indian edition of book "What Religion Is - In the Words of Swami Vivekananda," originally published in London in 1963 to commemorate Vivekananda’s birth centenary.The book was compiled by John Yale (Swami Vidyatmananda), who condensed nearly 4,200 pages from the eight volumes of Vivekananda’s Complete Works into a concise volume of under 100,000 words. The goal was to present Vivekananda’s vast thoughts on religion in a systematic, accessible, and authentic way for the modern mind.
