Form realm

Form realm (Skt. rūpadhātu; Wyl. gzugs khams) — the second of the three realms, only 'populated' by gods and divided into seventeen heavens. The cause for being reborn in one of these heavens is the favourable karma accumulated through the practice of one of the four dhyanas, each 'causal meditative dhyana' acting as a cause of rebirth in one of the corresponding 'resultant dhyana levels'.
