首楞嚴義疏注經 3.334

3.334

此明真色。初一句指本迷，如來下三句顯法體。如來藏，即一法界心中道第一義諦也。性色真空即俗之真，性空真色即真之俗。皆言性者，顯即中之真俗也。斯則舉一即具三、言三體即一，非縱橫竝別名祕密藏，此真地大也。清淨下二句敘德量，無妄相應，具無漏法故名清淨，非是有為故云本然，無所不在故云周遍。此則種性、體德、體量悉具足耳。若識此法，成三妙觀，方知一塵具一切佛法、一切心法、一切眾生法，靡不皆在一微塵中即見盧舍那。即見自己，即見一切法；如一微塵，一切法亦爾，下皆准此。隨眾生下顯隨緣也，眾生十界漏、無漏異，業亦不同，所感色法淨穢殊等也。

This clarifies true matter. The first line points to fundamental delusion; the three lines from 'within the tathāgatagarbha' onward reveal the substance of dharmas. The tathāgatagarbha is the one dharmadhātu mind, the Middle Way supreme truth. 'The nature of matter is true emptiness' is the ultimate within the conventional; 'the nature of emptiness is true matter' is the conventional within the ultimate. Stating 'nature' in both cases reveals the ultimate and conventional that are identical to the Middle. Thus, raising one fully possesses the three, and speaking of the three, their substance is one; being neither vertical nor horizontal, parallel nor separate, it is called the secret treasury. This is the true earth element. The two lines from 'pure' describe its virtues and magnitude: free of deluded correspondence and possessing undefiled dharmas, it is called pure; not being conditioned, it is said to be original; being nowhere absent, it is said to be all-pervading. Thus lineage, essential virtue, and essential magnitude are all fully complete. If one recognizes this dharma, one accomplishes the three wonderful contemplations, only then knowing that a single dust particle possesses all Buddha-dharmas, all mind-dharmas, and all sentient-being dharmas; none are not completely within a single subtle dust particle wherein one sees Vairocana. One directly sees oneself and directly sees all dharmas; as with a single dust particle, all dharmas are likewise so. What follows is based on this throughout. From 'according to the minds of sentient beings' onward reveals conforming to conditions: the ten realms of sentient beings differ in defilement and undefilement, their karma also differs, and the material dharmas they experience have distinct purities and impurities.
