大方廣圓覺修多羅了義經略疏 1.809

1.809

助謂資助，助正道故。道即是因，所謂止觀。品即是類，正因類故。亦云菩提分，分亦因義。三十七者，謂四念處、四正勤、四神足、五根、五力、七菩提分、八正道分。然但以十法為體，謂精進、定、慧各八，念四，戒三，信二，輕安、喜、捨、思惟各一。

'Aiding' means assisting, because they assist the correct path. The path is the cause, namely śamatha and vipaśyanā. 'Factors' means categories, because they are categories of the correct cause. They are also called 'factors of bodhi' (bodhipakṣika), where 'factors' also has the sense of causes. The thirty-seven are the four applications of mindfulness, the four right exertions, the four bases of psychic power, the five faculties, the five powers, the seven factors of awakening, and the eightfold noble path. However, they take only ten dharmas as their substance: diligence, samādhi, and prajñā have eight each; mindfulness has four; precepts has three; faith has two; and pliancy, joy, equanimity, and contemplation have one each.
