considered Buddha called Sun-Moon-Light, we consider how Sun-Moon-Light recited the Innumerable Teachings Sūtra and emitted a ray of light illumining eighteen thousand Buddha-worlds in the east just as Śākyamuni is illumining the Buddha-worlds.
“Maitreya, know this! All those Buddhas were called Sun-Moon-light with the ten epithets. Their expounding of the Dharma was good at the beginning, good in the middle, and good at the end. The last Sun-Moon-Light Buddha was once a king. He had eight sons born to him before he renounced the world. The first son was called Having-Intention; the second, Good-Intention; the third, Infinite-Intention; the fourth, Treasure-Intention; the fifth, Increasing-Intention; the sixth, Doubts-Removing-Intention; the seventh, Resounding-Intention; and the eighth, Dharma-Intention. These eight princes had unhindered powers and virtues. Each of them was the ruler of the four continents [of a Sumeru-world]. Having heard that their father had renounced the world and attained Anuttara-samyak-saṃbodhi, they abdicated from their thrones, and followed their father. They renounced the world, aspired for the Great Vehicle, performed brahma practices, and became teachers of the Dharma. They had already planted the roots of good under ten million Buddhas in their previous existence.
“Thereupon the last Sun-Moon-Light Buddha expounded a Sūtra of the Great Vehicle called the ‘Innumerable Teachings, the Dharma for Bodhisattvas, the Dharma Upheld by the Buddhas.’ Having expounded this sūtra, he sat cross-legged [facing the east] in the midst of the great multitude, and entered into the samādhi for the purport of the innumerable teachings. His body and mind became motionless.
“Thereupon the gods rained mandarava-flowers, maha-mandarava-flowers, manjusaka-flowers, and maha-manjusakaflowers upon the Buddha and the great multitude. The world of the Buddha quaked in the six ways. The great multitude of the congregation, which included bhikṣus, bhikṣunīs, upāsakās, upāsikās, gods, dragons, yakṣas, gandharvas, asuras, garuḍas, kiṃnaras, mahoragas, men, nonhuman beings, the kings of small countries, and the wheel turning-holy kings, were astonished. They rejoiced, joined their hands together [towards the Buddha], and looked up at him with one mind.
‘Thereupon the Tathagata emitted a ray of light from the white curls between his eyebrows, and illumined all the corners of eighteen thousand Buddha-worlds in the east just as this Buddha is illumining the Buddha-worlds as we see now.
