Bhaiṣajyarāja

Bhaiṣajyarāja (Skt: भैषज्यराज; Traditional Chinese: 藥王; Simplified Chinese: 药王; pinyin: yào wáng; Japanese: 薬王 Yakuō; Vietnamese: Dược Vương Bồ Tát), or Medicine King, is a bodhisattva mentioned within the Lotus Sutra and the Sūtra Spoken by the Buddha on Visualizing the Two Bodhisattvas Bhaisajyarāja and Bhaisajyasamudgata (Chinese: 佛說觀藥王藥上二菩薩經). In chapter 23 of the Lotus Sutra ("The Bodhisattva Bhaiṣajyarāja"), the Buddha retells a previous life of the Medicine King Bodhisattva, who burnt his body as a supreme offering to a buddha. He is said to have been reborn over a period of numerous lifetimes healing and curing diseases, and is a representation of the healing power of the Buddha.

In the Medicine Master Sūtra, he is one of the eight bodhisattvas in the retinue of the buddha Bhaiṣajyaguru.
