Kāraṇḍavyūha Sūtra
The Kāraṇḍavyūha Sūtra ("The Basket's Display", Full Sanskrit: Āryakāraṇḍavyūhanāmamahāyānasūtra, Tibetan: ['phags pa] za ma tog bkod pa zhes bya ba theg pa chen po'i mdo; Chinese: 佛說大乘莊嚴寶王經; pinyin: Fó shuō dàchéng zhuāngyán bǎo wáng jīng) is a Mantrayāna sūtra which extols the virtues and powers of Avalokiteśvara, who is presented here as a primordial cosmic overlord (a kind of adibuddha figure) and as the source of numerous Indian deities.
The Kāraṇḍavyūha was compiled at the end of the 4th century or beginning of the 5th century CE. It exists in Chinese translation (at Taishō Tripiṭaka no. 1050) and in Tibetan (Tohoku no. 116). This sutra is particularly notable for introducing the mantra Om mani padme hum and also teaching the important Cundi dharani.
