不增不減經云。甚深義者。即第一義諦。第一義諦者。即眾生界。眾生界者。即如來藏。如來藏者。即法身。釋曰。夫心者。為諸法總持之門。作萬有真實之性。故稱第一義諦。雜雜心念。故號眾生。是心之界。即眾生界。從真如性起。名曰如來。無所缺減。乃目為藏。能積聚恒沙功德。故名法身。是以仁王經云。最初一念。具足八萬四千波羅蜜。

The Anūnatvāpūrṇatvanirdeśasūtra states: “The profound meaning is the ultimate truth; the ultimate truth is the realm of sentient beings; the realm of sentient beings is the tathāgatagarbha; the tathāgatagarbha is the dharmakāya.” Explanation: The citta is the portal of total retention for all phenomena, acting as the true nature of myriad beings; hence it is called the ultimate truth. Because of miscellaneous mental thoughts, it is named “sentient beings”; the realm of this citta is the realm of sentient beings. Arising from the nature of tathatā, it is named the “Tathāgata”; being without any lack or decrease, it is regarded as the “store” (garbha); because it can accumulate merits as numerous as the sands of the Ganges, it is named the dharmakāya. Therefore, the Benevolent King Sūtra states: “The very first single thought is replete with the eighty-four thousand pāramitās.”
