...when you know this truth you will have eliminated the Mego.
The false-self is a liar, it tries to lie to who are (Enthoozee) and everyone around trying to make them believe their story. Who you are already knows this truth and sees right through their own falseness and no longer gives it any importance.
A liar can tell a lie and believe that others believe the lie. If another person believes the lie that is because they also are a liar. Who you are recognizes a liar as falseness.
Enthoozee is incapable of lying; so true Mego is incapable of telling the truth.
