There may be a strong element of clarity encompassing the anger. Finally, at the deepest level of experiencing, there is simply the pure energy of the anger, and no identification of location in the body. There is no feeling of oneself as an observer separate from the feeling. One's awareness is one with the feeling, which has no apparent source, nor anything outside it. There is no sense of time passing, and no experience of space as a container for things and events.
Space is simply nonextended openness.
