Suchness
In simple terms, to experience ourselves as Being is to experience
our existence as such, to experience our own Presence, our own
“suchness” directly. It is the simplest, most obvious,
most taken-for-granted perception that we exist. But this existence
is usually inferred, mediated through mind, as in Descartes’s
“Cogito ergo sum” – “I think, therefore
I am.” Existence is background, not foreground, for our
ordinary experience. To penetrate into this background, to question
our assumptions about reality and ourselves, allows us to encounter
directly the immense mystery of the arising of our consciousness
and of the world. (The Point of Existence, pg 19)

It is Suchness, pure Suchness. We cannot say anything about it.
We cannot say it is self, we cannot say it is not self, we cannot
say it is God, we cannot say it is the universe, we cannot say
it is a person, we cannot say it is not a person; the moment we
say anything, we are within mind. If we use any concept here,
even the concept of purity, simplicity, or whatever else, we are
within the mind, and we are blocking that which cannot be named.
