In Jain belief, the soul does not travel by a physical journey after all karmic bondage is destroyed. Here is the simple idea:

• Karma binds the soul to a cycle of birth and death. When all karmas are shed (that is, when bondage is completely exhausted), the soul is freed from rebirth.
• There is no need for a body or for traveling through the world after that. The liberated soul becomes a siddha (a perfected, blissful, omniscient being).
• A siddha resides in Siddha-loka, the realm of the liberated souls, beyond the cycles of time and space. There, the soul rests in its pure consciousness, free from karma, passions, and bodily limitations.
• The process to reach that state traditionally involves right faith, right knowledge, and right conduct (the three jewelled path), along with the shedding of karma through disciplines like austerities and ethical living. Once the last karma is shed, the soul’s nature shines in its true form and it ascends to siddha-loka, not through a mundane bodily journey.

Key points to hold:

• Moksha is the complete removal of karmic bondage, not just ending physical life.
• After bondage ends, the soul does not need a body or a world to travel through; it enters its own liberated state as a siddha.
• Digambar and Shwetambar traditions both affirm that moksha means eternal, perfect consciousness in Siddha-loka, though they describe aspects of the path and the nature of siddhas with traditional nuances.

If you’d like, I can give a concise summary of the exact scriptural terms used in Digambar and Shwetambar sources to describe siddha-loka and moksha.
