Bodhyāṅga

bodhyāṅga (Pāli, bojjhaṅga). A list of seven factors that lead to or constitute bodhi, or awakening. Often referred to as the seven ‘limbs of enlightenment’, the seven items are listed in Pāli sources as:

(1) mindfulness (sati);

(2) investigation of the Dharma (dharma-vicaya);

(3) energy (viriya);

(4) joy (pīti);

(5) tranquillity (passaddhi);

(6) meditation (samādhi);

(7) equanimity (upekkhā).

The seven occur as the sixth of the 37 ‘factors of enlightenment’ (bodhi-pākṣika-dharma).
