A Ray is a perceptible energy, though its presence is often subtle. Only individuals whose attention is tuned to the nuances of the Fourth and Fifth Dimensions may readily detect the esoteric existence of a Ray. Through personal experience, conscious understanding, and various states of awareness and manifestation students refine their ability to recognize the presence of Ray Forces. According to Ascended Master teachings, Ray Forces are present in every aspect of human endeavor; these energies influence the physical, psychological, emotional, and psychic essence of mankind. Rays are said to dispense Karma and direct spiritual evolution—individually and collectively.
