Master Hongyi's words: If I am not in it, I will be incompetent; If there is no one outside, there is no fault; It means (personal point of view): If you see yourself without me, you will see your essence in vain, and your understanding of yourself will not be affected by your own thinking. Look at yourself in the mirror, not moved by foreign things, not overwhelmed by others.

You said, "there is me inside, but there is no me outside." Personally, I think that before you belong to Master Hongyi's field, you should stare at yourself and don't be moved by foreign things. If you know better, you will have no me and no one.
