It is said that when the Bhaisajya-guru Buddha achieved enlightenment, the top of his head emitted a radiance tens of thousands of feet high, his mouth chanted incessantly, the earth shook, and any beings the light shone on became free of pain.
傳說藥師佛成佛的時候，他頭頂上放出萬丈光明，口裡不停念著：要用藥治療一切眾生病苦，使他立即痊癒。當時大地都震動起來，而且出現了萬丈光明，光明所照的眾生病苦全都消除。
