According to the Mahavadana Sutra, the six previous Buddhas to have appeared on this earth are:

• Vipasyi or Vipassi:

Vipasyi was born 91 kalpas ago to a family of the Khattiya (warrior) caste. His clan name was Kondanna. He was enlightened under a patali, or trumpet flower, tree.

• Sikhi

Sikhi was born 31 kalpas ago, also to a family of the Khattiya caste. He also was of the Kondanna clan, and he was enlightened under a pundarika, or artemisia, tree.

• Visvabhuj or Vessabhu.

Visvabhuj also was born 31 kalpas ago to a family of the Khattiya caste. Also of the Kondanna clan, he was enlightened under a sal tree.

• Krakucchanda or Kakusandha. 

Krakucchanda and the remaining three Buddhas were born during the current kalpa, but still an unimaginably long time ago. Krakucchanda was of the Brahmin, or priest, caste. He and the remaining three Buddhas also were of a clan called Kassapa. He was enlightened under an acacia tree.

• Kanakamuni or Konmagamana. 

Another member of the Brahmin caste, Kanakamuni was enlightened under an udumbara, or cluster fig, tree.

• Kasyapa or Kassapa. 

Another Brahmin, Kasyapa was enlightened under a banyan tree. He should not be confused with a disciple of Buddha Sakyamuni by the same name; the Buddha’s disciple Kasyapa usually is called Mahakasyapa, or Great Kasyapa, to distinguish him.

• Buddha Sakyamuni. 

The Buddha who’s teaching we currently study and practice.
