The Teaching on the Effulgence of Light
Initiated by the questions of the bodhisattva Candraprabhakumārabhūta, The Teaching on the Effulgence of Light consists of a series of teachings related to the lights emitted by awakened beings as manifestations of their spiritual achievements. Amid the display of his miraculous powers, the Buddha describes the specific qualities with which each of those lights is associated, and he repeatedly emphasizes the fact that such lights are a natural expression of the insight into the emptiness of all phenomena. The sūtra is also concerned with general themes such as the qualities required by followers of the Great Vehicle and the practice of generosity.
