THAT all humans possess an immortal soul is a common belief of humanity, but to this Theosophy adds we do not just ‘have’ souls, but each of us is a soul.
Further that we are an indivisible and indissoluble part of the consciousness of great nature which is also, by degrees, both conscious and intelligent.
And flowering into an Adept like Jesus or Buddha and manifesting those soul powers is perfectly possible to all human beings.
The driving power behind such development is what the ancients called the “Father which is in secret” (Matthew ch. vi. v. 6) in its esoteric meaning, and is not an extra-cosmic god.
“That ‘Father’ is in man himself,” Mme. Blavatsky wrote in the Key to Theosophy, unrestricted by age, social status or gender.
Our inner spiritual self “is the only God we can have cognizance of,” and she asks: “how can this be otherwise? — Grant us our postulate that God is a universally diffused, infinite principle, and how can man alone escape from being soaked through by, and in, the Deity?”
“We call our ‘Father in heaven’ that deific essence of which we are cognizant within us, in our heart and spiritual consciousness, and which has nothing to do with the anthropomorphic conception we may form of it in our physical brain or its fancy:”
“Know ye not that ye are the temple of God, and that the spirit of (the absolute) God dwelleth in you?” Yet, let no man anthropomorphize that essence in us. Let no Theosophist, if he would hold to divine, not human truth, say that this ‘God in secret’ listens to, or is distinct from, either finite man or the infinite essence — for all are one.”
