Yes. In Jainism, liberation (moksha) is possible for the soul while it is still alive, a state called jivanmukti. A jivanmukta is a soul that has destroyed all karmic bonds and attained pure right knowledge, vision, and conduct, and lives in a liberated, unhindered awareness even while it remains in the world. Eventually, the body may perish or the soul may complete its final release; the key point is that liberation is achievable during life for those who fully purify themselves.

Note:

• Both Digambar and Shwetambar traditions acknowledge the possibility of jivanmukti, though their descriptions and examples may differ in emphasis.
• In Jain cosmology, there are also souls who attain complete liberation (moksha) and reside in siddhashila after final release; jivanmukti refers specifically to liberation attained in this life.

If you’d like, I can also share a short, traditional verse (arth) that describes the liberated state, or point you to Jain sources that discuss jivanmukti in detail.
