You need not oppose the ego or struggle against it.
The ego is a part of your mind that has an illusory existence that you believe real.
Illusion need not be opposed; opposition merely strengthens it.
By your opposition you make it real, and this is a continuation of the problem not a solution.
The belief that illusions are real is what gives them their seeming power over you.
Let the Holy Spirit teach you the unreality of illusions, and do not resist His teaching.
You have believed in illusion since time began; your mind is very attached to what it has made.
Illusions will not disappear in a day.
With patience, and the willingness to learn what is true and what is illusion and the difference between them, all illusion will be steadily undone through the consistent choice of Truth with the help of the Holy Spirit.
Nothing more is needed but also nothing less.
