This text is the publisher's note for a compilation of Swami Vivekananda’s lectures and writings on Buddha and Buddhism. It highlights Vivekananda’s deep spiritual kinship with Buddha, whom he considered his Ishta (chosen ideal) and the perfect embodiment of India’s ancient wisdom.

The note details Swamiji’s lifelong devotion, from a youthful vision of Buddha to his pilgrimage to Bodh Gaya. He admired Buddha’s "boundless compassion" and "fearless quest for Truth," often presenting him to Western audiences as the ultimate spiritual exemplar. The book is structured in two parts: primary lectures and scattered observations. Ultimately, the publisher suggests that the collection reveals not just the history of Buddhism, but the "power and beauty" of Vivekananda’s own illumined mind.
