Where does a non-tirthankara jiva go after moksha?
In Jainism, moksha means liberation from the cycle of birth and death. A non-tirthankara jiva who attains moksha becomes a siddha (a perfected soul) and dwells in Siddha-loka (the realm of liberated souls). There, the jiva has a pure, formless existence, infinite bliss, and omniscience, without any further karma or rebirth. It remains in this Siddha state eternally, without activity or travel to other realms.
