I offer you these simple equations to ponder. Think of the Japanese koan (a tool of Zen Buddhism). My purpose is to stimulate your thought process, not to start a discussion or (God forbid) a ‘debate’ on the intellectual merits of this material. Just relax, cogitate, see what ‘comes up’ for you . . . .
Ego = Human Personality = Head = Lower Mind = Separation/Illusion/Material Consciousness
Spirit = Divine Personality = Heart = Higher Mind = Oneness/Christ/Divine Consciousness
