The Illusory Absorption Sutra
The Illusory Absorption (Skt. Māyopamasamādhi, Tib. སྒྱུ་མ་ལྟ་བུའི་ཏིང་ངེ་འཛིན།, Wyl. sgyu ma lta bu'i ting nge 'dzin) is found in the General Sūtra (mdo sde) section of the Tibetan Kangyur (Toh 130).
In this brief sūtra the Buddha explains the meditative state known as the "illusory absorption". He summons two bodhisattvas, Avalokiteśvara and Mahāsthāmprāpta, from the realm of Sukhāvatī, and recounts the story of how they first engendered the mind of awakening (bodhicitta).
