Dipankara
Dipankara Buddha, also known as the Lamp Bearer, is one of the Buddhas of the past. He is said to have lived on Earth four asankheyyas and one hundred thousand kappas ago. That's a long time! According to some Buddhist traditions, Dipankara was a previous Buddha who attained Enlightenment eons prior to Gautama Buddha, the historical Buddha.
Generally, Buddhists believe that there has been a succession of many Buddhas in the distant past and that many more will appear in the future. Dipankara was one of these previous Buddhas, while Gautama Buddha was the current and most recent Enlightened one, and Maitreya will be the next Buddha in the distant future.
Chinese Buddhism honors Dipankara as one of many Buddhas of the past. Dipankara, Gautama, and Maitreya are "the Buddhas of Three Times" in Yiguandao.
