If a jeev is in charmavart kaal, within how many bhav's does he get moksh?
If you mean ચરમાવર્તકાળ in Jain terminology, then there is no fixed number of bhav’s for moksha. It means the soul has reached the final stage of samsara, and liberation becomes possible when the required right faith, right knowledge, right conduct, and karma-kshaya are complete. ( jainqq.org)
In Jain usage, ચરમશરીરી means “the one who attains moksha in the same bhav”. So moksha can happen in that very bhav, but it is not a universal rule that every soul in charamavart gets moksha within a fixed number of bhavs. It depends on the soul’s karma and intense spiritual effort. ( jainqq.org)
So the simple answer is: no fixed bhav count; for a charamshariri, moksha may happen in the same bhav. ( jainqq.org)
