Strange though it may seem, the fact is that Buddhist scholars are engrossed too much in the study of what they regard as the Buddha’s teaching and his disciples’ exposition of the Dharma, so called, while they neglect altogether the study of the Buddha’s spiritual experience itself. According to my view, however, the first thing we have to do in the elucidation of Buddhist thought is to inquire into the nature of this personal experience of the Buddha, which is recorded to have presented itself to his inmost consciousness at the time of Enlightenment (_sambodhi_). What the Buddha taught his disciples was the conscious outcome of his intellectual elaboration to make them see and realise what he himself had seen and realised. This intellectual outcome, however philosophically presented, does not necessarily enter into the inner essence of Enlightenment experienced by the Buddha. When we want, therefore, to grasp the spirit of Buddhism, which essentially develops from the content of Enlightenment, we have to get acquainted with the signification of the experience of the founder,—experience by virtue of which he is indeed the Buddha and the founder of the religious system which goes under his name. Let us see what record we have of this experience, and what were its antecedents and consequences.[f48] There is a Sutra in the Dīgha-Nikāya known as the _Mahāpadāna Suttanta_, in which the Buddha is represented as enlightening his disciples concerning the six Buddhas anterior to him. The facts relating to their lives as Bodhisattvas and Buddhas are almost identical in each case except some incidental details; for the Buddhas are all supposed to have had one and the same career. When therefore Gautama, the Buddha of the present Kalpa, talks about his predecessors in this wise, including the story of Enlightenment, he is simply recapitulating his own earthly life, and everything he states here as having occurred to his predecessors, except such matters as parentage, social rank, birthplace, length of life, etc., must be regarded as also having happened to himself. This is especially true with his spiritual experience known as Enlightenment.[f49]
