"Rather than trying to prolong the moment of awareness, we simply rely on short moments of awareness, repeated many times, until it becomes automatic. The moment will grow longer on its own. It is a matter of emphasizing the presence of awareness rather than emphasizing points of view.
Everpresent like the sun in the sky, the instinctive recognition of awareness is available to us wherever we are."
