This book describes the Buddhism of India on the basis of the comparison of all the available original sources in various languages. It falls into three approximately equal parts. The first is a reconstruction of the original Buddhism presupposed by the traditions of the different schools known to us. It uses primarily the established methods of textual criticism, drawing out of the oldest extant texts of the different schools their common kernel. This kernel of doctrine is presumably common Buddhism of the period before the great schisms of the fourth and third centuries BC. It may be substantially the Buddhism of the Buddha himself, though this cannot be proved: at any rate, it is a Buddhism presupposed by the schools as existing about a hundred years after the Parinirvana of the Buddha, and there is no evidence to suggest that it was formulated by anyone other than the Buddha and his immediate followers. The second part traces the development of the 'Eighteen Schools' of early Buddhism, showing how they elaborated their doctrines out of the common kernel. Here we can see to what extent the Sthaviravada, or 'Theravada' of the Pali tradition, among others, added to or modified the original doctrine. The third part describes the Mahayana movement and the Mantrayana, the way of the bodhisattva and the way of ritual. The relationship of the Mahayana to the early schools is traced in detail, with its probable affiliation to one of them, the Purva Saila, as suggested by the consensus of the evidence. Particular attention is paid in this book to the social teaching of Buddhism, the part which relates to the 'world' rather than to nirvana and which has been generally neglected in modern writings of Buddhism.
