My studies leave me wondering if there is a "feminine" or if it is a metaphor for something else. On page 124 of the Urtext of A Course In Miracles Jesus states:

"This is the invitation to the Holy Spirit. I told you that I could reach up and bring the Holy Spirit down to you. But I can bring Him to you only at your own invitation. The Holy Spirit is nothing more than your own right mind. He was also mine. The Bible says, “May the mind be in you that was also in Christ Jesus,” and uses this as a BLESSING. It is the blessing of miracle-mindedness. It asks that you may think as I thought, joining with me in Christ-thinking.

The Holy Spirit is the only part of the Holy Trinity which is symbolic. He is referred to in the Bible as the Healer, the Comforter, and the Guide. He is also described as something separate, apart from the Father and from the Son. I myself said, “and if I go I will send you ANOTHER comforter, and he will abide with you.

The Holy Spirit is a difficult concept to grasp, precisely because it IS symbolic, and therefore open to many different interpretations. As a man and as one of God’s creations, my right thinking, which came from the Universal Inspiration which IS the Holy Spirit, taught me first and foremost that this Inspiration is for ALL. I could not have it myself without knowing that."

Page 125 (I capitalized the first sentence.)

"THE MIRACLE ITSELF IS JUST THIS FUSION OR UNION OF WILL BETWEEN FATHER AND SON." "The Holy Spirit, the shared Inspiration of all the Sonship, induces a kind of perception in which many elements are like those in the Kingdom of Heaven Itself."

......

As such, I suspect it is simply a re-joining or witness of the impossibility of the separation. Countering the error of the belief of separation from God/Father.

May I suggest it may be the literal "birthing" of Christ as we each accept our role in that body and thus accept our true existence, eventually to all be "birthed" and "awaken" to our unity as the Son? Beloved, innocent, perfect, and with an inheritance of all that the Father has.

Sexuality is an ego construct manifested because the ego is incapable of truly creating.
