In Jainism, sukha (bliss) that comes with kevala jnana is considered anant sukha — infinite bliss that accompanies perfect, unobstructed knowledge of the soul. It is a natural by‑product of a cleansed jiva (soul) when all karmic veilings are removed. This bliss is tied to the liberated soul itself and does not imply an external absolute or non-dual reality in the way Advaita describes Brahman. Digambaras and Śvetāmbaras agree that kevala jnana brings supreme joy along with omniscience, though they may differ in some details about the nature and expression of a kevalin’s existence.
