The positions advocated by Mahayana [great vehicle] Buddhism, which distinguishes itself from the Theravada and related schools by calling them Hinayana [lesser vehicle], evolved from other of the early Buddhist schools. The Mahayana emerges as a definable movement in the 1st cent. B.C., with the appearance of a new class of literature called the Mahayana sutras. The main philosophical tenet of the Mahayana is that all things are empty, or devoid of self-nature (see sunyata). Its chief religious ideal is the bodhisattva, which supplanted the earlier ideal of the arahant, and is distinguished from it by the vow to postpone entry into nirvana (although meriting it) until all other living beings are similarly enlightened and saved.
The bodhisattva is an actual religious goal for lay and monastic Buddhists, as well as the name for a class of celestial beings who are worshiped along with the Buddha. The Mahayana developed doctrines of the eternal and absolute nature of the Buddha, of which the historical Buddha is regarded as a temporary manifestation. Teachings on the intrinsic purity of consciousness generated ideas of potential Buddhahood in all living beings. The chief philosophical schools of Indian Mahayana were the Madhyamika, founded by Nagarjuna (2d cent. A.D.), and the Yogacara, founded by the brothers Asanga and Vasubandhu (4th cent. A.D.). In this later Indian period, authors in different schools wrote specialized treatises, Buddhist logic was systematized, and the practices of Tantra came into prominence.
