The vital is the Life-nature made up of desires, sensations, feelings, passions, energies of action, will of desire, reactions of the desire-soul in man and of all that play of possessive and other related instincts, anger, fear, greed, lust, etc., that belong to this field of nature.
The vital being and the life-force in man are separated from the Divine Light and, so separated, they are an instrument for any power that can take hold of them, illumined or obscure, divine or undivine.
Mind and vital are mixed up on the surface of the consciousness, but they are quite separate forces in themselves and as soon as one gets behind the ordinary surface consciousness one sees them as separate, discovers their distinction and can with the aid of this knowledge analyse their surface mixtures. It is in the vital that thought is transformed into will and becomes a dynamism for action.
This is the world in which thou mov'st, astray
In the tangled pathways of the human mind,
In the issueless circling of thy human life,
Searching for thy soul and thinking God is here.
But where is room for soul or place for God
In the brute immensity of a machine ?
