The Authentic is authentic, no doubt

Your essence is authentic.

The expressions are relative.
Believed in as being separate and special, they appear to create a problem.
For whom?

My ordinary advice is this:
As often as possible, stay with the quiet essential nature of your natural presence, even if only for a few minutes. Drop all ideas of being 'someone'.
Let it be simply - openness.
A sense of vastness may be witnessed.
Let it be.

Then resume your 'normal' activities.
Witnessing is happening.
No witness. No objects.

Simple wakefulness.
