The term mind is used to represent the activating agent of spirit, with the spirit supplying its creative energy.
In this world, because the mind is split, the Sons of God appear to be separate. Nor do their minds seem to be joined. In this illusory state, the concept of an “individual mind” seems to be meaningful. It is therefore described in the course as if it has two parts; spirit and ego.
Spirit is the part that is still in contact with God through the Holy Spirit, Who abides in this part but sees the other part as well. The term “soul” is equivalent of “spirit,” with the understanding that, being of God, it is eternal and was never born.
The other part of the mind is entirely illusory and makes only illusions. Spirit retains the potential for creating, but its Will, which is God’s, seems to be imprisoned while the mind is not unified. However, creation continues unabated because that is the Will of God. This Will is always unified and therefore has no meaning in this world. It has no opposite and no degrees.
Very few people appreciate the real power of the mind. Nobody remains fully aware of it all the time.
The mind is a very powerful creator, and it never loses its creative force. It never sleeps. Every instant it is creating, and ALWAYS as you will.
