Yes, according to Jainism, a kevalin (one who has attained kevala jnana or omniscience) is fully aware of the fact that he has attained kevala jnana. Kevala jnana is the state of infinite, perfect knowledge, free from all karmic obstructions. A kevalin experiences direct, complete, and unobstructed knowledge of all substances and their modes in the universe, across all times.

Jain texts explain that with the destruction of the four ghatiya karmas (knowledge-obscuring, perception-obscuring, deluding, and obstructive karmas), the soul shines in its true nature. The kevalin is completely aware of this liberation from karmic bondage and the perfection of knowledge. Thus, self-awareness of omniscience is inherent to the state of a kevalin.
