What is real never was born nor dies, never changes, does not come and go.
What is real can never be negated or denied.
What is unreal does not exist.
What changes, what was born and dies, what comes and goes, is unreal.
The world, the body, the thoughts - all these change, come and go, are born and die. All these can be negated, even the knowledge of them is subject to change.
What is the only thing that can never be negated? What is the only thing in a lifetime of experience that has never changed?
It is YOU. Your Self. You have never changed, you have never come and gone. You are the Reality while the world, body and thoughts come and go as appearance.
You are that to which appearance comes and goes. You are that reality which IS while the world, body and thoughts are only appearance.
Your relationship to the world, body and thoughts is that of awareness of them. They come and go because you are PRESENT and AWARE.
Therefore the world, body and mind are nothing BUT the EXPERIENCING of them. The experiencing of the world, body and mind IS what we "call" awareness. They are not separate things that you are aware OF. The very experience itself IS Awareness.
There is no experience vs. experiencing. These are one and the same reality, always.
Therefore the world, body and thoughts are apparent comings and goings OF your Self. Before you called it "world, body, and thoughts", it had no label of separate-ness. Before you called it "experience" it had no separate-ness.
It is only the habitual concept which seems to bind. Therefore the only liberation is seeing the concept as unreal, as learned, as not actual.
How do you come to see or realize this? Allow that, maybe for the first time, to be the subject of inquiry. Don't assume it's already true and then use it as a platform from which to inquiry. Inquire into the nature of the foundation itself.
What comes and goes is not real. You are the only thing that never comes and goes, throughout a lifetime of experience. Find out what it is that never changes.
