The phenomenon works on basis of sympathetic resonance between oscillating systems. The systems in this case being localised points of consciousness within the unified quantum field of awareness, which is all pervading, omnipotent and beyond linear time.
The point of realised potential of the initiator connects and conducts its enhanced vibrational state to the aspirant which gets attuned to it. The evolved potential of the adept conveys its focused & charged conscious life force (prana) to that of the seeker, which is scattered and diluted.
The combined interference of vibrations activate the inherent infinite charge of the seeker, making it more focused and concentrated, pushing it beyond the threshold, underneath which Kundalini potential lies dormant.
