As long as it is still anchored in the individual consciousness of body-life-mind, the psychic awareness is subject to the limitations implicit in the lower manifestation. Additionally, the initial development of the psychical consciousness takes place in spurts and starts, and remains incomplete, subject to confusion, gaps of information, and misdirection or misinterpretation due to the distorting influences of the mind and the vital consciousness, or the predilections of the ego-awareness and the insistence of the desire-soul. With the shift of the standpoint to the supramental level of awareness, all of these deficiencies are cured through the clarity, power and knowledge attendant to that level of consciousness.
Sri Aurobindo notes: “The psychical consciousness is first supported and enlightened, then filled and occupied with the supramental light and power and the revealing intensity of its vibrations. Whatever exaggeration, whatever error born of isolated incidence, insufficiently illumined impression, personal suggestion, misleading influence and intention or other cause of limitation or deformation interferes in the truth of the mental and psychical experience and knowledge, is revealed and cured or vanishes, failing to stand in the light of the self-truth– satyam, rtam — of things, persons, happenings, indications, representations proper to this greater largeness. All the psychical communications, transcriptions, impresses, symbols, images receive their true value, take their right place, are put into their proper relations. The psychical intelligence and sensation are lit up with the supramental sense and knowledge, their phenomena, intermediate between the spiritual and material worlds, begin to reveal automatically their own truth and meaning and also the limitations of their truth and significance. The images presented to the inner sight, hearing, sensation of all kinds are occupied by or held in a larger and more luminous mass of vibrations, a greater substance of light and intensity which brings into them the same change as in the things of the physical sense, a greater totality, precision, revealing force of sense knowledge carried in the image. And finally all is lifted up and taken into the supermind and made a part of the infinitely luminous consciousness, knowledge and experience of the supramental being, the Vijnana Purusha.”
