Cí-shì Púsà 慈氏菩薩 (“the Compassionate-One Bodhisattva”) is the Chinese translation of Sanskrit Maitreya (“the Friendly One”), the bodhisattva who in Mahāyāna cosmology dwells in the Tuṣita heaven awaiting his future descent to earth as the next Buddha. The same person is also referred to as 彌勒菩薩 (彌勒菩薩) — the phonetic transliteration. In the East Asian Mahāyāna doctrinal tradition, Maitreya is canonically credited as the original “speaker” (說 shuō) of the Yogācārabhūmi texts on the bodhisattva-path, including the Pú-sà-jiè-běn (KR6k0122 / KR6k0123) corpus on the bodhisattva-precepts. The attribution is doctrinal-revelatory rather than historical: the texts are presented as Maitreya’s revelations transmitted through Asaṅga 無著 (the historical author).
