Yes, they describe different ideas in Jainism vs. Advaita Vedanta.

• Kevala jnana sukha (in Jainism)

- Meaning: The bliss that accompanies kevala jnana—the complete, omniscient knowledge of a Tirthankara or a liberated soul. It is a state of perfect wisdom (kevala jnana) and the associated peace and happiness that come with shedding all delusion and bondage. - Nature: It is a spiritual, transformative experience tied to liberation (moksha) and the end of karmic bondage. It is inseparable from the realization of the true nature of the jiva (soul) and its freedom from craving, anger, and attachment. - Focus: Internal discipline, right knowledge, right faith, and right conduct; the bliss arises from purifying the soul and removing karmic impurities.

• Advaita ananda (in Advaita Vedanta)

- Meaning: “Non-dual bliss” arising from the realization of the oneness of Atman (the self) with Brahman, the ultimate reality. It is the bliss of non-dual awareness. - Nature: Ontological/metaphysical: the individual self is not really separate from the universal Self; bliss is the experience of this non-dual reality. - Focus: Attainment of a non-dual awareness, often described as realization that there is only one reality (Brahman), beyond dualities like subject-object, pleasure-pain.

Key difference

• Groundedness: Kevala jnana sukha is rooted in Jain epistemology (jiva, karma, liberation) and is about the purified, omniscient knowledge of a liberated soul. Advaita ananda is rooted in non-dual metaphysics (Brahman) and the oneness of all existence.
• Metaphysical frame: Jainism preserves a plurality of jivas and a karma-driven path to moksha; Advaita asserts a single, non-dual reality.
• Goal orientation: In Jainism, the goal is liberation from samsara through right knowledge, right faith, and right conduct. In Advaita, the goal is realizing non-dual awareness of the self’s identity with Brahman.

If you’d like, I can explain how Digambar and Shvetambar views express kevala jnana and its bliss differently within Jain scriptures.
