Avatamsaka Sutra (Skt. Avataṃsakasūtra; Tib. མདོ་ཕལ་པོ་ཆེ་, do palpo ché, Wyl. mdo phal po che) or Buddhavatamsaka Sutra (Skt. Buddhāvataṃsaka-sūtra), 'The Sutra of the Ornament of the Buddhas' — one of the most important (and largest) of all Mahayana sutras. It includes the Sutra of the Ten Bhumis and the Gandavyuha Sutra, which in turn includes Samantabhadra's Aspiration to Good Actions.
The Tibetan version in 45 chapters forms a whole section (named Ornaments of the Buddhas section) of the Sutra section of the Kangyur and spans four volumes.
The text was translated in Tibetan in the 9th century by Surendra and Vairocana Rakṣita.
