大方廣佛華嚴經隨疏演義鈔 77.35

77.35

疏「四即三念處行」者，亦云三念住。念謂能緣之慧，處謂不增不減平等之理。初一心聽法不憂、二一心聽法不喜、三常行捨心，以法界中減退相不可得故、增進相不可得故、即涅槃相故，如次配之。疏「三後善謂究竟離垢等故」者，等字等取及一切究竟離欲，為後邊故、法性離垢故、能學者亦離垢故、修行究竟得離垢故。

Regarding the Commentary's statement "the fourth is the practice of the three stations of mindfulness": they are also called the three dwellings of mindfulness. "Mindfulness" refers to the wisdom that can observe; "station" refers to the impartial principle that neither increases nor decreases. 1. Single-mindedly listening to the Dharma without sorrow; 2. single-mindedly listening to the Dharma without joy; 3. constantly practicing an equanimous mind. Because in the dharmadhātu marks of decrease cannot be apprehended, marks of increase cannot be apprehended, and it is identical to the mark of nirvāṇa, they are matched in this order.

Regarding the Commentary's statement "third, good in the end means ultimately free from defilement, etc.": the word "etc." includes by extension: "and reaching the ultimate limit of being completely free from desire," "because the nature of phenomena is free from defilement," "because those capable of learning are also free from defilement," and "because practice ultimately attains freedom from defilement."
