仁王護國般若波羅蜜多經疏 2.203

2.203

解曰：此聖位也。言信忍者，謂證信也。此位菩薩親證真如，三寶及戒皆證淨故，故此三地俱名信忍。雖後諸地亦有此四，此初現證得證淨名，加行後得多緣此故。言歡喜者，初獲聖性具證二空，能益自他生大喜故。所言地者，依持生長、如智相應，至下當悉。離垢地者，具淨尸羅，遠離能起微細毀犯煩惱垢故。發光地者，成就勝定大法總持，能發無邊妙慧光故。從此第一正解修行。於中分二：且初第一明斷三障。

Exposition: These are the noble stages. As for "faithful kṣānti," it refers to verified faith. Because bodhisattvas of this stage personally realize tathatā, and the Three Jewels as well as morality are all purified through realization, these three bhūmis are therefore all named "faithful kṣānti." Although the subsequent bhūmis also possess these four, this is the initial direct realization that attains the name "purified through realization," as subsequent to the preparatory stage they mostly take this as their cognitive object. As for "Joyous": having first attained the noble nature and fully realized the two emptinesses, they are able to benefit themselves and others, producing great joy. As for "ground" (bhūmi): it serves as support and generates growth, where suchness and cognition are in correspondence, as will be fully explained below. As for the "Stainless Ground": possessing pure morality (śīla), they are far removed from the defiling afflictions that can give rise to subtle infractions. As for the "Luminous Ground": accomplishing superior concentration and the dhāraṇī of the Great Dharma, they are able to emit the light of boundless, wondrous wisdom. First from here is the proper exposition of cultivation. It is divided into two: first is explaining the severing of the three obstacles.
