The Ornament of the Light of Awareness that Enters the Domain of All Buddhas
The sūtra known as The Ornament of the Light of Awareness that Enters the Domain of All Buddhas (Skt. Sarvabuddhaviṣayāvatārajñānālokālaṃkāra, Tib. སངས་རྒྱས་ཐམས་ཅད་ཀྱི་ཡུལ་ལ་འཇུག་པའི་ཡེ་ཤེས་སྣང་བའི་རྒྱན།, Wyl. sangs rgyas thams cad kyi yul la ’jug pa’i ye shes snang ba’i rgyan) is found in the General Sūtra (mdo sde) section of the Tibetan Kangyur (Toh 100).
In this sūtra the Buddha, by the use of similes, explains how all things, buddhas included, share the same nature of emptiness, and how the illusory Buddha dispenses teachings with great compassion.
