Empty: No Form
In advaita, we learn that there is no birth and no death. Why? Because birth and death can apply only to something which has (or has had) existence, and advaita makes clear that no such separate entity exists.
Ajata makes the entire situation clearer: there is not (and never has been) anything from the start. Why? Because from utter nothingness, or total and complete emptiness, there cannot ever be anything at all. This is not “empty space”: there is no space, where not anything exists at all. In total nothingness, there is no such thing as time: this is not nothingness that has an “existence”; where the possibility of existence does not apply, neither does the quality (or lack of) “nonexistence” apply.
The point is that in nothingness we do not say that “you” exist: nor do we say that “birth” is a reality or that “death” is a reality.
So, in ajata we do not say that there is birth and death; nor would we say that there is no birth and no death.
Further, in ajata we would not say “form is emptiness, emptiness is form”—although this has practicality in teaching nonduality. In the true emptiness of nothingness there cannot be any forms.
Where nothingness is the absolute and ultimate condition, all “things”—real or unreal, material or nonmaterial, conceived or inconceivable—are not actually any thing, or are “empty of reality”.
So, the so-called realization or experience of sunyata puts to rest every question or controversy that you can assume to have.
All of it is empty.
