What you are seeking is already here and now.
Yet it cannot be pointed out as a "thing". Any "thing" is a relative appearance.
The sense of ME isn't it. That is another "thing" appearing, another speck of knowledge, assumption, abstraction.
The body-mind isn't it. That is also another "thing" appearing, a bundle of concepts with no real or absolute separate existence.
What you are seeking is already fully present, yet it isn't any of these "things" you've identified with. It isn't a "thing" as such, because any "thing" has no real existence apart from what you are seeking.
What you are seeking, is the totality of whatever is appearing, whatever it is, whatever the "content" of this moment is.
You are this very moment, itself.
Yet "within" this moment, everything changes. All "things" are only as such because of conceptualization, assumption, abstraction, inferences, beliefs. There is only an "outside world" and separation because of this thought-process going on IN this very moment.
You are not the appearances or the thoughts. You are this moment, this "container", this Presence IN WHICH these "things" seem to happen, come and go.
Whether or not they are conceptualized, whether or not there is a belief formed in thought or not, whether or not there is a belief in a separate ME and a WORLD, makes absolutely no difference. "Self-realization" isn't "necessary" because whether there is "understanding" or not, you are still already only ever THIS.
THIS is it. THIS is all there ever is. YOU are THIS.
So the beliefs created in thoughts fall away and leave this no-thing-ness or they don't - it makes absolutely no difference. There is no "you", no separate individual, to do anything to "get it", to "make it happen", to "find out what you are".
You ARE. That's it. There is nothing to do to "get it". It is already unavoidable. You cannot NOT be what you are.
