"Who am I?" is not really a question because it has no answer to it; it is unanswerable. It is a device, not a question.
There is nothing in existence available without payment. If you want to know yourself, you will have to drop all false identities. They are your investments, they are your power, they are your prestige, they are your religion, they are your qualifications. It is difficult to drop them; it feels like death.
