Lets say you are an atom. Being enlightened is like if the atom was aware of its own nature as infinite potential. So wherever this atom goes and no matter what other atoms it witnesses, it witness them as ‘ITSELF’ in a different possibility (one of its own possibilities).
In the illustration below:
First atom 1 sees itself as 1, and sees all other atoms as different from itself. Then on enlightenment, the atom realizes it contains within its nature the potential to be every other atom in existence.
