bodhipakkhiya-dhammā: The 37 'Things pertaining to Enlightenment', or 'requisites of enlightenment' comprise the entire doctrines of the Buddha. They are:

(1) the 4 Foundations of Mindfulness (Satipaṭṭhāna, q.v.),
(2) the 4 Right Efforts (s. padhāna),
(3) the 4 Roads to Power (iddhi-pāda, q.v.),
(4) the 5 Spiritual Faculties (indriya; s. bala),
(5) the 5 Spiritual Powers (bala, q.v.),
(6) the 7 Factors of Enlightenment (bojjhaṅga, q.v.),
(7) the Noble 8-fold Path (s. magga).

In M. 77 all the 37 bodhipakkhiya-dhammā are enumerated and explained though not called by that name. A detailed explanation of them is given in Vis.M. XXII. In S.XLVII, 51, 67, only the five spiritual faculties (indriya) are called bodhipakkhiya-dhammā; and in the Jhāna Vibhaṅga, only the 7 factors of enlightenment (bojjhaṅga).
