The karmāśaya of both kinds described above ripens into life-state, life-time and life-experience. These are called the three ripenings or vipākas of the karmāśaya; and they are conducive to pleasure or pain, according as they are products of puṇyakarmāśaya (virtue) or pāpa karmāśaya (vice or demerit). Many karmāśayas combine to produce one life-state; for it is not possible that each karma should produce one or many life-states, for then there would be no possibility of experiencing the effects of the karmas, because if for each one of the karmas we had one or more lives, karmas, being endless, space for obtaining lives in which to experience effects would not be available, for it would take endless time to exhaust the karmas already accumulated. It is therefore held that many karmas unite to produce one life-state or birth (jāti) and to determine also its particular duration (āyush) and experience (bhoga). The virtuous and sinful karmāśayas accumulated in one life, in order to produce their effects, cause the death of the individual and manifest themselves in producing his rebirth, his duration of life and particular experiences, pleasurable or painful. The order of undergoing the experiences is the order in which the karmas manifest themselves as effects, the principal ones being manifested earlier in life. The principal karmas here refer to those which are quite ready to generate their effects. Thus it is said that those karmas which produce their effects immediately are called primary, whereas those which produce effects after some delay are called secondary. Thus we see that there is continuity of existence throughout; when the karmas of this life ripen jointly they tend to fructify by causing another birth as a means to which death is caused, and along with it life is manifested in another body (according to the dharma and adharma of the karmāśaya) formed by the prakṛtyāpūra (cf. the citta theory described above); and the same karmāśaya regulates the life-period and experiences of that life, the karmāśayas of which again take a similar course and manifest themselves in the production of another life and so on.
