金剛般若經旨贊 2.79

2.79

經。若復有人至其福勝彼　贊曰。下校量經福。於中有二。初舉劣校量。後況復勝行。此初也。於中法行各起四行。自作教他讚勵慶慰。其慶慰者是隨喜。由隨喜故信心不迷。迷者即是不隨喜義。既能隨喜故心不迷。

Sūtra: "If, again, someone... his merit surpasses that." / Commentary: Below is weighing the merit of the sūtra. Within it there are two: first, citing the inferior to weigh it; later, how much more so for the superior practice. This is the first. Within it, each dharma practice gives rise to four practices: doing it oneself, teaching others, praising and encouraging, and rejoicing. Rejoicing is muditā. Because of rejoicing, one's faithful mind is not confused. Confusion means not rejoicing; since one can rejoice, one's mind is not confused.
