Choosing and discriminating
The intellectual aspect of God is the right-brain/left-brain, thinking, creative, and rational self. The Intellectual Aspect of God chooses and discriminates on a moment by moment basis. Choosing to direct energy of creation. Deciding how to evolve.
This Aspect is a matter of problem for many people because it can be a series cloud presenting an illusion of separateness from God. Many, if not most, people in their day to day lives would say that their intellect belongs to them and their Ego and is in no way connected as an Aspect of God. I (my Ego!) would say differently. When my intellect is at its clearest, it is directly, intimately, connected to God.
Ego is a cloudy film on this aspect of God.
