Sutra on Wisdom at the Hour of Death
The Sūtra on Wisdom at the Hour of Death (Skt. Atyayajñānasūtra, Tib. འདའ་ཀ་ཡེ་ཤེས་ཀྱི་མདོ།, Wyl. 'da' ka ye shes kyi mdo) is found in the General Sūtra (mdo sde) section of the Tibetan Kangyur (Toh. 122).
In this brief sūtra the Buddha, residing in the Akaniṣṭha realm, by the use of similes, explains to bodhisattva mahāsattva Ākāśagarbha the wisdom that should be cultivated by the bodhisattva when about to die.
