However, sometimes Daath is seen to be the First or Crown Sephirah instead of Keter. From this viewpoint, Daath is the reflection (from the perspective of finite creation) of the infinity of Keter.
For this reason Daath is placed on the middle axis of the Tree of Life; directly beneath Keter. It corresponds to the tzelem Elokim (the "image of God embedded in Humanity") and to the cerebellum-the "posterior brain."
Because all ten sephirot in the Tree of Life are united as one in Daath, the three sephirot of the left-hand column of the Tree, that would normally receive and conceal the Divine Light, share and reveal it instead. The sephira are no longer distinguishable from each other.
In a perfect world, the Divine Light would always be shining through its Creation; the Light is indeed there-but not all humans can see it. Whether the Divine Light of Creation is concealed or revealed through Daath does not take place in Daath itself. It only seems that way from the human perspective with Malkuth. The revelation of the Divine Light can only occur in Malkuth (our world).
People who become self-giving like the Light are able to perceive it, and for them the tremendous Knowledge of Daath's light seems "revealed." However, humans who are self-centered can't perceive the Light, and for them its Knowledge seems "hidden."
