Vibratory Expansion

ALICE A. BAILEY: White Magic, page
352: “When one lesson has, in this way, been mastered, a further one is set, and when a pupil has learnt a particular series of lessons he graduates and passes an initiation.  The whole group he teaches is benefited by his step forward, for every disciple carries those he instructs along with him in a curious indefinable sense.  The benefit to the unit reacts upon the whole.  A Master carries His disciples on and up with Him in a similar manner.  The matter is abstruse and largely one of the secrets of the law of vibratory expansion.  The initiation of the Logos has a universal effect.”
