八相成道

(八相) also 八相示現 Eight aspects of the Buddha's life, which the 起信論 gives as:

(1) descent into and abode in the Tuṣita heaven;

(2) entry into his mother's womb;

(3) abode there visibly preaching to the devas;

(4) birth from mother's side in Lumbinī;

(5) leaving home at 19 (or 25) as a hermit;

(6) after six years' suffering attaining enlightenment;

(7) rolling the Law-wheel, or preaching;

(8) at 80 entering nirvāṇa. The 四教義 group of Tiantai is slightly different -- descent from Tuṣita, entry into womb, birth, leaving home, subjection of Māra, attaining perfect wisdom, preaching, nirvana. See also the two 四相, i.e. 四本相 and 四隨相.
