The confirmations of the Spirit are all those powers and gifts which some are born with (and which men sometimes call genius), but for which others have to strive with infinite pains. They come to that man or woman who accepts his life with radiant acquiescence.
The “nameless name” is sometimes referred to as “the Word” (“In the beginning was the Word …”) and “the unstruck sound” of Vedic scriptures.
Sixth, the world of humanity is in need of the confirmations of the Holy Spirit. True distinction among mankind is through divine bestowals and receiving the intuitions of the Holy Spirit. If man does not become the recipient of the heavenly bestowals and spiritual bounties, he remains in the plane and kingdom of the animal. 317 For the distinction between the animal and man is that man is endowed with the potentiality of divinity in his nature, whereas the animal is entirely bereft of that gift and attainment. Therefore, if a man is bereft of the intuitive breathings of the Holy Spirit, deprived of divine bestowals, out of touch with the heavenly world and negligent of the eternal truths, though in image and likeness he is human, in reality he is an animal; even as Christ declared, “That which is born of the flesh is flesh; and that which is born of the Spirit is spirit.” This means that if man be a captive of physical susceptibilities and be lacking the quickening of spiritual emotions, he is merely an animal. But every soul who possesses spiritual susceptibilities and has attained a goodly portion of the bestowals of the Holy Spirit is alive with the divine life of the higher Kingdom. The soul that is portionless and bereft is as dead. Therefore, He said, “Let the dead bury their dead.” Just as the physical body of man is in need of its force of life, even so the human soul is in need of the divine animus and vivification emanating from the Holy Spirit. Without this vivification and sustenance, man would be an animal, nay, rather, dead.
