Buddha means “awakened one” and specifically refers to Shakyamuni Buddha, also known as Siddhartha Gautama (traditional date, sixth c. BCE), the historical founder of the tradition that became known as Buddhism. All Buddhist traditions agree that there have been many Buddhas, but the Mahayana and Vajrayana traditions particularly emphasize that Shakyamuni is only one of a variety of Buddhas. Other prominent Buddhas include Amitabha, Bhaishajya-guru, and Vairochana.
