The body, life and mind in the human individual form around an ego-consciousness. A frame or barrier is created of an apparently real separation, which both protects the individual from the impact and bombardment of the powers at work in the creation, and creates limitations on the action of the material consciousness that lives within this frame. While the consciousness is maturing, it may be admitted that this apparent separation serves a purpose and provides protection; yet the limitation is real, and there results considerable opportunity for misunderstanding and mistakes in general when these limited formations interact with one another as if they are separate, each out for his own aggrandisement and satisfaction.
With the development of the supramental consciousness, the inherent oneness of the entire creation, and all its forms, becomes clear and incontrovertible, and each of the supposedly separate forms is recognized as being part of a greater whole and responding to the forces that move throughout the creation, among and between and within those forms.
The supramental action is able to remove these fictitious walls of separation and thus, recognize and consciously participate in the free movement of awareness, energy and force between all the aspects and participants in the creation. The result is to overcome the limitations caused by apparent separation and give the being new and expanded powers of awareness, understanding and action.
Sri Aurobindo notes: “The supramental transformation extends too the physical consciousness far beyond the limits of the body and enables it to receive with a perfect concreteness the physical contact of things at a distance. And the physical organs become capable of serving as channels for the psychic and other senses so that we can see with the physical waking eye what is ordinarily revealed only in the abnormal states and to the psychical vision, hearing or other sense knowledge. It is the spirit or the inner soul that sees and senses, but the body and its powers are themselves spiritualised and share directly in the experience. The entire material sensation is supramentalised and it becomes aware, directly and with a physical participation and, finally, a unity with the subtler instrumentation, of forces and movements and the physical, vital, emotional, mental vibrations of things and beings and feels them all not only spiritually or mentally but physically in the self and as movements of the one self in these many bodies. The wall that the limitations of the body and its senses have built around us is abolished even int he body and the senses and there is in its place the free communication of the eternal oneness. All sense and sensation becomes full of the divine light, the divine power and intensity of experience, a divine joy, the delight of the Brahman.”
