Spirit has no levels
ACIM
...You are also incapable of knowledge because you can still perceive lovelessly.
Perception did not exist until the separation introduced degrees, aspects and intervals. Spirit has no levels, and all conflict arises from the concept of levels. Only the Levels of the Trinity are capable of unity. The levels created by the separation cannot but conflict. This is because they are meaningless to each other.
Consciousness, the level of perception, was the first split introduced into the mind after the separation, making the mind a perceiver rather than a creator. Consciousness is correctly identified as the domain of the ego. The ego is a wrong-minded attempt to perceive yourself as you wish to be, rather than as you are. Yet you can know yourself only as you are, because that is all you can be sure of. Everything else is open to question.
The ego is the questioning aspect of the post-separation self, which was made rather than created. It is capable of asking questions but not of perceiving meaningful answers, because these would involve knowledge and cannot be perceived. The mind is therefore confused, because only One-mindedness can be without confusion.
A separated or divided mind must be confused.
