Bhava: 'becoming', 'process of existence', consists of 3 planes: sense-existence kāma-bhava, fine-material existence rūpa-bhava, immaterial existence arūpa-bhava. Cf. loka.
The whole process of existence may be divided into two aspects:
- Kamma-making kamma-bhava, i.e. the kammically active side of existence, being the cause of rebirth and consisting in advantageous and disadvantageous intentional actions. See Kamma, paticca-samuppāda IX.
- Kamma-produced rebirth, or regenerating process uppattibhava, i.e. the kammically passive side of existence consisting in the arising and developing of the kamma-produced and therefore morally neutral mental and bodily phenomena of existence. Cf. Tab. - App..
Bhāva: feminine and masculine 'nature', refers to the sexual characteristics of the body, and belongs to the group of materiality see: khandha. It is a commentarial term for the abilities of femininity and masculinity see: indriya 7, 8. App..
