I paid attention to the slight shifts between headlessness and being with experiences today. They are very similar, although in being with the form is slightly more in the foreground, and in headlessness the awake emptiness is slightly more in the foreground. And of course, within each, there are also shifts in which of the two are more in the foreground.
I also noticed a curiosity about how it is when both are more fully present, and had that answered a few minutes later when I walked into the public library and listened to a surprisingly good live performance of baroque chamber music (Bach, Corelli etc.). The sound, which was full, rich and clear as water, evoked a similar sense of fullness of being at human and soul levels, and also brought into the foreground the awake emptiness.
So at once, there was a deep and rich sense of fullness of being, as an individual, and also the awake emptiness within which and as all form arises. A fullness of being as individual, and also the field arising absent of a separate self.
