Prana

Prana — the Life Principle, the breath of Life. The occultist believes the following statement: "Life we look upon as the one form of existence, manifesting in what is called matter, or what, incorrectly separating then we name Spirit, Soul, and Matter in man. Matter is the vehicle for the manifestation of soul on this plane of existence; soul is the vehicle for the manifestation of spirit, and these three as a trinity are synthesised by Life, which pervades them all."

(Alice A. Bailey "Initiation, Human and Solar")
