It is important to understand that with the development of the supramental awareness comes an entire difference in the nature and action of the consciousness. Some have called this a “reversal” of consciousness, or have indicated that for the yogi, day is night and night is day in relation to the ordinary mental consciousness. These differences arise due to the standpoint from which these respective statuses start and the reference they make back to their own viewpoint of the nature of reality.
The mental consciousness is not ordinarily aware of the wholeness of all creation, and does not use that as the framework or basis for reviewing and judging facts and events. The supramental consciousness, on the other hand, starts from the standpoint of unity with the Divine and the oneness of all creation. Clearly this implies a totally different process of knowing and a completely different result in action.
Sri Aurobindo observes: “The essential truths of self and the spirit and the principle of things are not to the spiritual reason abstract ideas or subtle unsubstantial experiences to which it arrives by a sort of overleaping of limits, but a constant reality and the natural background of all its ideation and experience. it does not like the mind arrive at, but discloses directly both the general and total and the particular truths of being and consciousness, of spiritual and other sensation and Ananda and of force and action,– reality and phenomenon and symbol, actuality and possibility and eventuality, that which is determined and that which determines, and all with a self-luminous evidence. It formulates and arranges the relations of thought and thought, of force and force, of action and action and of all these with each other and throws them into a convincing and luminous harmony. It includes the data of sense, but gives to them another meaning in the light of what is behind them, and treats them only as outermost indications: the inner truth is known to a greater sense which t already possesses. And it is not dependent on them alone even in their own field of objects or limited by their range. It has a spiritual sense and sensation of its own and it takes and relates to that the data too of a sixth sense, the inner mind sense. And it takes also the illuminations and the living symbols and images familiar to the psychic experience and relates these too to the truths of the self and spirit.”
