Which past Buddha is said to have predicted Shakyamuni’s enlightenment? The answer is Dipankara.
Dipankara, whose name means “Lamp Bearer,” is regarded in Buddhist tradition as a Buddha of the distant past. In the well-known prediction story, the future Gautama Buddha appears in an earlier life as the ascetic Sumedha. When Dipankara encounters him, Sumedha lies across a muddy path so the Buddha can pass without getting dirty.
Impressed by Sumedha’s devotion and aspiration, Dipankara foretells that he will one day become a Buddha known as Shakyamuni, born among the Shakya people. This prophecy marks Sumedha’s formal entry into the long bodhisattva career that eventually culminates in Gautama Buddha’s enlightenment.
Dipankara is therefore not Shakyamuni’s teacher in the historical lifetime described by early Buddhist biography. He is a predecessor from a remote cosmic past. Buddhist traditions differ in their lists and stories of past Buddhas, but Dipankara’s prediction is especially prominent in Jataka literature and Buddhist art, where Sumedha is often shown kneeling with his hair spread across the ground.
