Some of the ways there is, and is not, a separate self…
Finding ourselves as emptiness, there is an absence of a separate self… and anything else for that matter. The void is void.
Finding ourselves as awake emptiness and form, and form as no other than awake emptiness itself, there is also an absence of a separate self. There is just one field of awake emptiness and form, with no more or less identification with any part of it. This human self senses, thinks, acts in the world, but there is only the doing and no doer there. It all happens on its own, as part of the field.
Within form, there is also no separate self. There is just a seamless field of form, with infinite causes and infinite effects to anything happening locally… including anything happening to, within and as this particular human self.
And finally, within form, there is a separate self. This human self exists within the world of form. It is a whole as well as a part of a much larger whole. It is a holon in a holarchy. And in that sense, there is a separate self, or rather a separate individual living, relating and behaving in the world.
It is just that this separate self is not really separate from the wider world of form, nor is there a local doer there, nor is it anything else than emptiness itself.
All together, there is emptiness awake to itself and the inherent absence of a separate self in anything. There is the seamless whole of the world of form, with everything local having infinite causes and effects. And there is also the differentiation of this human individual from the wider world, allowing it to function in the world with a particular identity (an identity used for differentiation only, seen as only a relative, utilitarian, limited and temporary, truth.)
