Anupurvi (आनुपूर्वी) refers to a class of karmas in Jainism called "anupurvi nama-karmas." These are the karmas that determine the jiva’s next birth and its realm (deva, manusya, tiryak) after the current life ends.

Key points:

• Anupurvi nama-karma can be of four kinds based on the birth realm: deva (heavenly beings), manusya (humans), tiryak (animals/birds/reptiles), and naraka (hell beings).
• These karmas govern the direction of rebirth: after death, the soul moves to the new birth in the chosen realm according to the type of anupurvi karma it has accumulated.
• This concept is the same in both major Jain traditions (Digambara and Śvetāmbara), though texts and details may vary slightly in different scriptures.
