五種法界

The Huayan school's five forms of (sa) dharmadhātu:

(1) 有為法界 or 事世界 the phenomenal realm;

(2) 無為法界 or 理世界 the dependent and interactive; the inactive, quiescent, or noumenal realm;

(3) 亦有為亦無為世界 or 事理無礙世界, both, i.e., interdependent and interactive;

(4) 非有為非無為世界 either active nor inactive, but it is also 事理無礙世界, e. g. water and wave, wave being water and water wave;

(5) 無障礙世界 or 事事無礙世界 the unimpeded realm, the unity of the phenomenal and noumenal, of the collective and individual.
