Who am I?

Ask yourself: "Who am I?"

Do not answer with the mind. Do not say "I am a person" or "I am consciousness." These are thoughts about I, not I itself.

When thoughts arise, ask: "To whom does this thought arise?" The answer is: "To me."

Then inquire: "Who is this me? Who am I?"

Return to the source of the I-thought. Abide there. Let all other thoughts subside.

What remains when thought is absent? That which is aware of the absence of thought—what is that?

Rest in that.
