We should experience everything totally, never withdrawing into ourselves as a marmot hides in its hole.
This practice releases tremendous energy which is usually constricted by the process of maintaining fixed reference points. Referentiality is the process by which we retreat from the direct experience of everyday life.
Being present in the moment may initially trigger fear. But by welcoming the sensation of fear with complete openness, we cut through the barriers created by habitual emotional patterns.
If we find that we are disturbing ourselves in any of these ways, we stop meditating and simply rest or relax for a while. Then we resume our meditation. If we have "interesting experiences" either during or after meditation, we should avoid making anything special of them. To spend time thinking about experiences is simply a distraction and an attempt to become unnatural. These experiences are simply signs of practice and should be regarded as transient events. We should not attempt to re-experience them because to do so only serves to distort the natural spontaneity of mind.
All phenomena are completely new and fresh, absolutely unique and entirely free from all concepts of past, present and future. They are experienced in timelessness.
In meditation we can see through the illusion of past, present and future - our experience becomes the continuity of nowness. The past is only an unreliable memory held in the present. The future is only a projection of our present conceptions. The present itself vanishes as soon as we try to grasp it. So why bother with attempting to establish an illusion of solid ground?
