Ibn Arabi—This Sufi mystic indicates the necessity for “divine unveiling” ("kashf") as the means by which to understand the universality of the reality of realities (i.e. the universality of God’s oneness). In "fana" (self-annihilation), the individual ego passes away and divine self-manifestation occurs. This self-manifestation is eternal (as it comes from God), but it must be continually reenacted by the human in time. Therefore, the human becomes a pure receptor required for pure consciousness to be realized. The human is a sort of "barzakh" or intermediary between divinity and elementality, between spirit and matter, and open to the experience of "kashf".
