“As your concentration deepens, you gain the ability to see thoughts and sensations arising slowly, like separate bubbles, each distinct and with spaces between them. They bubble up in slow motion out of the unconscious. They stay a while in the conscious mind and then they drift away.
The application of awareness to mental states is a precision operation. This is particularly true of feelings or sensations. It is very easy to overreach the sensation. That is, to add something to it above and beyond what is really there. It is equally easy to fall short of sensation, to get part of it but not all. The ideal that you are striving for is to experience each mental state fully, exactly the way it is, adding nothing to it and not missing any part of it. Let us use pain in the leg as an example. What is actually there is a pure flowing sensation. It changes constantly, never the same from one moment to the next. It moves from one location to another, and its intensity surges up and down. Pain is not a thing. It is an event. There should be no concepts tacked on to it and none associated with it. A pure unobstructed awareness of this event will experience it simply as a flowing pattern of energy and nothing more. No thought and no rejection. Just energy.”
