The journey into the Earth plane is the same for strong angels as it is for all Celestial beings. But strong angels suffer the fall of all mankind as if it were their own for they are the guardians of the human race and must endure the pain of the innocent.
Every human being is an angel, fallen: a strongangel has stood upright many times.
Think of your self as a strong angel. You will not be wrong to do so. You are able to rise up from the ground and allow the shroud of worldliness to slip.
