From: The Flower Ornament Scripture, Book One
Thus have I heard. At one time the Buddha was in the land of Magadha, in a state of purity, at the site of enlightenment, having just realized true awareness. The ground was solid and firm, made of diamond, adorned with exquisite jewel discs and myriad precious flowers, with pure clear crystals. The ocean of characteristics of the various colors appeared over an infinite extent. There were banners of precious stones, constantly emitting shining light and producing beautiful sounds. Nets of myriad gems and garlands of exquisitely scented flowers hung all around. The finest jewels appeared spontaneously, raining inexhaustible quantities of gems and beautiful flowers all over the earth. There were rows of jewel trees, their branches and foliage lustrous and luxuriant. By the Buddha's special power, he caused all the adornments of this enlightenment site to be reflected therein.
The tree of enlightenment was tall and outstanding. Its trunk was diamond, its main boughs were lapis lazuli, its branches and twigs were of various precious elements. The leaves, spreading in all directions, provided shade, like clouds. The precious blossoms were of various colors, the branching twigs spread out their shadows. Also the fruits were jewels containing a blazing radiance. They were together with the flowers in great arrays. The entire circumference of the tree emanated light; within the light there rained precious stones, and within each gem were enlightening beings, in great hosts like clouds, simultaneously appearing.
Note: The Flower Ornament Scripture (Avatamsaka Sutra), is a text of immense importance and influence in East Asian Mahayana Buddhism. It is thought to have been authored by multiple individuals in northern India during the first and second centuries AD. The English translation is by Thomas Cleary. The text has been described by Cleary as "the most grandiose, the most comprehensive, and the most beautifully arrayed of the Buddhist scriptures.” The Flower Ornament Scripture describes a cosmos of infinite realms upon realms filled with an immeasurable number of Buddhas. It served as the foundation of the Huayan school of Chinese Buddhism, which is known in Japan as Kegon. The sutra was highly influential in Chan and Zen Buddhism.
