This book is a review from the February 1900 issue of the journal Mind, discussing Swami Abhedananda’s work on reincarnation.

The discourse explores how the ancient Indian doctrine of rebirth relates to concepts of evolution and justice, noting its growing influence on Western thought. It credits India as the essential source of this vital spiritual knowledge. The author presents reincarnation as a "universal solvent" for life’s mysteries, providing logical answers to profound questions that often baffle great thinkers. Specifically, it seeks to reconcile the scientific law of evolution with the existence of a just Creator, challenging the idea that a person has only one lifetime to achieve spiritual self-consciousness. Ultimately, the book is highly recommended for all deep thinkers.
