The grosser consciousness depends heavily on particles of matter. The subtler consciousness is more independent -- it does not depend so much on the brain. Luminance, radiance, imminence -- the three states of subtle mind -- all of these disappear in the clear Light, the innermost consciousness.
When a person is poised in all three centers (mind, heart, and body), balanced and alertly there, a shift happens in consciousness. Rather than being trapped in our usual mind, with its well-formed rut tracks of issues and agendas and ways of thinking, we seem to come from a deeper, steadier, and quieter place. We are present, in the words of Wisdom tradition, fully occupying the now in which we find ourselves.
This state of presence is extraordinarily important to know and taste in oneself. For sacred tradition is emphatic in its insistence that real Wisdom can be given and received only in a state of presence, with all three centers of our being engaged and awake. Anything less is known in the tradition as "sleep" and results in an immediate loss of receptivity to higher meaning. To return to that favorite Wisdom metaphor, it is like the disciple Peter suddenly sinking beneath the surface of the waters.
