To "know its own nature" is to recognize this divine lineage and potential, to understand that "as above, so below" applies to the microcosm of the human soul mirroring the macrocosm of the universe. This recognition breaks the illusion of separation and ignorance, which the Gnostics often referred to as slumber or death. Awakening, therefore, is the realization of one's true, divine identity, shedding the veils of material existence and illusion.
