In Shakyamuni Buddha's time, Buddhism had not split into Mahayana and Hinayana, though Mahayana ideas were already circulating. The distinction between Mahayana and Hinayana and their later developments reflect the different ways of interpreting the Buddha's ideas and the precepts. While Hinayana Buddhism is a conservative form of Buddhism that adheres to Pali scriptures and the Buddha's original teachings, Mahayana Buddhism emphasizes the Bodhisattva spirit in delivering senting beings and transforming the world.
