The Avataṃsaka Sūtra (Sanskrit: महावैपुल्यबुद्धावतंसकसूत्र Mahāvaipulya Buddhāvataṃsaka Sūtra) is one of the most influential Mahayana sutras of East Asian Buddhism. The title is rendered in English as Flower Garland Sutra, Flower Adornment Sutra, or Flower Ornament Scripture.
The Avataṃsaka Sūtra describes a cosmos of infinite realms upon realms, mutually containing one other. The vision expressed in this work was the foundation for the creation of the Huayan school of Chinese Buddhism, which was characterized by a philosophy of interpenetration.
