Buddhism in its course of development has completed a form which distinguishes itself from its so-called primitive or original type—so greatly, indeed, that we are justified in emphasizing its historical division into two schools, Hinayana and Mahayana, or the Lesser Vehicle and the Greater vehicle of salvation. As a matter of fact, the Mahayana, with all its varied formulae, is no more than a developed form of Buddhism and traces back its final authority to its Indian founder, the great Buddha Sakyamuni.
