In this spirited defense of Mahayana Buddhism, Daisetz Teitaro Suzuki challenges Western misconceptions and invites readers into the tradition's spiritual and historical depth. He presents Mahayana and Hinayana as two great developments from a common Buddhist source: one expansive, speculative, and progressive; the other more conservative and ethically rationalistic. Their differences, he argues, are not contradictions but natural expressions of Buddhism's growth across India and Asia, shaped by different temperaments and needs. Suzuki traces Mahayana's original meaning as the highest spiritual principle and highlights the Bodhisattva ideal of compassionate enlightenment for the sake of all beings. He also examines core doctrines such as non-self, karma, consciousness, Suchness, and Nirvana, while defending Mahayana against critics who rely too narrowly on Pali texts or misunderstand its ideas of heaven, merit, and salvation. At the heart of the book stands the Dharmakaya: not an empty abstraction, but the living, all-pervading reality underlying existence, named in forms such as Vairocana and Amitabha. Blending scholarship with religious conviction, Suzuki presents Mahayana as a living faith whose historical development proves its vitality and authenticity.
