Solve the Mystery and the Misery of ‘Me’

You have to solve the mystery and the misery of being ‘me’.

It’s the personal witness that says: ‘I like this. I don’t like that’.
The personal sense of self acts as a witness also, but it only witnesses with self-interest.
Is there awareness of this or not?

Can the person itself be observed?
What knows and observes that the person is not consistent?
That which perceives the person—is that itself personal or impersonal?
