When there is a realization of selflessness, there is also the realization of the inseparability of Ground and phenomena. Any and all forms are Ground themselves. Ground temporarily taking a particular form.
One of these phenomena is of course our human self, so our human self - along with anything else - arises within and as Ground, awareness, emptiness, Buddha Mind, Spirit, Brahman.
The Ground, awareness, emptiness, Buddha Mind, Spirit, Brahman is naturally in the foreground. Anything arising is inherently and primarily this. The particulars of the form itself, and especially its names and associations, are secondary although easily available.
Nothing needs to change in content. Ground allows anything to arise as and within our human self. Yet, an awakening to selflessness also allows our human self to reorganize and realign to this new context.
There is a sense of infinite distance to this human self, of absence of any identification, of any sense of I there. It arises as everything else arises. Sensations and thoughts comes and goes as everything else comes and goes. It lives its own life, as everything lives its own life. It does, but there is no doer there. It chooses, but there is no chooser there. This human self, its experiences, its actions, just happens, as everything else just happens.
At the same time, there is a sense of intimacy - even more intimate than any intimacy since there is an absence of I and of Other. This human self arises as Ground. There is an absence of separation. An absence of I. An absence of Other. An absence of distance. It is more intimate than the most intimate. It is on the other side of intimacy, since there is an absence of all of this.
