四善根

catuṣ-kuśala-mūla, the four good roots, or sources from which spring good fruiy or development. In Hīnayāna they form the stage after 總相念住 as represented by the 倶舍 and 成實; in Mahāyāna it is the final stage of the 十廻向 as represented by the 法相宗. There are also four similar stages connected with (sa) śrāvaka, (sa) pratyekabuddha, and Buddha, styled 三品四善根. The four of the 倶舍宗 are 煗法, 頂法, 忍法, and 世第一法. The four of the 成實宗 are the same, but are applied differently. The 法相宗 retains the same four terms, but connects them with the four (sa) dhyāna stages of the 真唯識觀 in its four first 加行 developments.
