佛說觀佛三昧海經 9.17

9.17

Then the Buddhas of the ten directions descended from the sky, emitting thousands of rays of light, displaying the light of their form-bodies' white ūrṇā mark. Each sat on the seat of Śākyamuni Buddha, and each stretched out his right hand, stroked Ānanda's crown, and addressed him: "Son of the Dharma! Your master and preceptor Śākyamuni undertook hundreds of thousands of austerities and countless vigors to seek the Buddha's wisdom and obtain this body as a retribution. Its luminous physical marks are now being expounded for you. You must uphold the Buddha's words and, for the devas, nāgas, the great assembly, monks, nuns, laymen, and laywomen of future ages, extensively expound the method of contemplating the Buddha and the mindfulness-of-the-Buddha samādhi." Having spoken these words, they then inquired after Śākyamuni Buddha: "Are your daily activities peaceful and at ease?" Having inquired, they emitted great rays of light and each returned to his own land.
