Question: To what degree should our ego develop to reach discovery of the Creator?
Answer: Our ego needs to be developed to the point where it covers the whole world. In other words, I connect with everything in this world—inanimate, vegetative, animals, and human beings—and absorb their egosim, their characteristics, within me, and correct them within me.
This is a state where I see that the whole world is just a projection of my uncorrected internal characteristics, and when I correct them, they are already in me.
