如來說法 The Tathāgata Expounds the Dharma
眾菩薩獻畢,因請如來明示根本,指解源流。那如來微開善口,敷演大法,宣揚正果,講的是三乘妙典,五蘊楞嚴。但見那天龍圍繞,花雨繽紛。正是:众菩萨献毕,因请如来明示根本,指解源流。那如来微开善口,敷演大法,宣扬正果,讲的是三乘妙典,五蕴楞严。但见那天龙围绕,花雨缤纷。正是:

The bodhisattvas, their offerings done, then begged the Tathāgata to reveal the fundamental and expound the source.
明示根本,指解源流 — show us the root, untangle the source. It is a polite way of asking for the deepest thing he has.
The Tathāgata, gently opening his benign lips, set forth the Great Dharma and proclaimed the true fruit, expounding the wondrous canon of the Three Vehicles and the Five Aggregates of the Śūraṅgama.
三乘 (sān shèng) are the three vehicles; 五蘊 the five aggregates, the skandha a person is assembled from; 楞嚴 is the Śūraṅgama Sūtra.
One saw only the heavenly dragons wheeling round and a riot of flower-rain. Truly:
花雨 is the rain of blossom that falls in the sūtras whenever the preaching is good enough — applause from the universe.
The Chan-mind shines clear — a moon upon a thousand rivers;
千江月: one moon, a thousand rivers, a thousand reflections, and still one moon. The stock Chan picture for a single nature turning up in every separate thing.
the true nature, limpid, holds the sky of ten thousand li.
真性 is the true nature and 清涵 its clear holding. A mind with ten thousand li of sky in it — room without contents, which is the point.
The preaching is staged as a show before it is offered as doctrine: dragons circling, blossom falling, and then a closing couplet that boils the whole sermon down to one image. The narrative is clearing its throat for the chapter's central act, the decision to send the scriptures east.
That couplet — 禪心朗照千江月,真性清涵萬里天 — is among the finest lines in the chapter. The moon on a thousand rivers is the standard Chan emblem for one buddha-nature refracted through countless minds; paired with a clear sky that holds ten thousand li, it makes waking up both a reflection and a capacity. Yu notes how such couplets work as lyric punctuation, freezing the action into a held breath.
