In the teachings of awareness and the "I am", what is being spoken of is really the sense of self, the sense of separation. The "untouched awareness" is a disassociated me appearance, believing itself to be the source of it all. In some teachings this disassociated me is even revered. It is the me worshiping itself. A self created story, perpetuating its own sense of existence.
The trouble with these teaching is that this experience of untouched awareness never seems to last. So the seeker goes back to the teacher to seek again. This whole play goes on rinse and repeat. Perpetual seeking. Trying to find an end and believing the untouched witness is that end. In reality there is no end as there is no one to have an end.
