Hmmm? It could very well be our mind is the activity of Mind = Holy Spirit. See the following – pages 1 -3 of first part and page 6 of the first lesson from the class series, “Releasing the Holy Spirit of God in Man” (unpublished Fillmore, Unity Archives, #3232, 1931)
From page 1 and 2“… we will immediately discern that we have within us those three activities of mind, the Father Mind [Mind], the Son mind [Christ = Idea], and the Holy Spirit [Expression]. In other words, the mind [Mind] and the idea [Idea] and the manifestation [Manifestation] of that idea. These three come in every one of us. And, we, being the offspring of this Mind who moves in this s0-called mysterious way, can readily locate ourselves in this One Presence and unfold whatever is in the principle [Principle], unfold it in ourselves and unfolding it in ourselves, of course, we can tune in with this universal mind.”
In the context of this series the Idea = Christ = the Idea that is made up of the Twelve Powers. The important piece is that we ARE all three. At least at this point in the talk. Now let’s look at page 6
“This mind is incorporating and expressing through its thoughts and activity the great Omnipresent Mind of God. Think of yourself in a larger way than you have before. Quit thinking about yourself as a limited personal being. Think about yourself as Spirit; as the Holy Spirit. And what is that? It means the Holy Spirit. People say, “Do you mean to say that man is the Holy Spirit or God?” Yes, certainly. All that the Father has He has given to the Son. God is Spirit, and all this Spirit is involved in our consciousness, just waiting for our recognition; and faith is the recognition of the mind in a realm beyond its present capacity to assimilate.”
