This book, Universal Religion and Vedanta, is a compilation of eight lectures delivered by Swami Abhedananda between 1904 and 1922. It presents a scholarly and scientific exploration of Vedantic philosophy, framing it as the "Sanatana Dharma"—an eternal religion.

A key argument is that because Vedanta has no single human founder, it remains free from the limitations of personality and sectarianism. The Swami emphasizes that Vedantic teachings are uniquely broad-based and in perfect harmony with modern scientific truths. Ultimately, the text positions Vedanta as the only truly universal religion, capable of embracing all seekers. It is presented as an essential resource for those pursuing a rational, inclusive, and deep understanding of spiritual truth.
