大乘起信論裂網疏 4.32

4.32

真如者，體大也。無量無漏者，相大也。勝境界用者，用大也。眾生之心全攬真如體大為體，故本具此相大用大也。如人迷方，方仍不動。如水成氷，氷之濕性如故，則融相潤用亦復本具，即此名為阿賴耶中無漏種子。譬如氷中融潤之性，不離於氷而與氷違。所以無漏道起，則捨賴耶及異熟名也。

"Tathatā" is the greatness of essence. "Immeasurable untainted [qualities]" is the greatness of attributes. "The function of superior cognitive objects" is the greatness of function. Sentient beings' minds wholly assume the greatness of essence of tathatā as their essence, and so are fundamentally replete with this greatness of attributes and greatness of function. Just as when a person loses their direction, the direction itself remains unmoved; and just as when water turns into ice, the wet nature of the ice remains as before, so that the mark of melting and the function of moistening are also fundamentally replete—this is precisely what is called the untainted seeds in the ālayavijñāna. It is like the melting and moistening nature in ice, which is not separate from the ice yet opposes the ice. Therefore, when the untainted path arises, the names "ālaya" and "vipāka" are cast off.
