A synopsis of the Maamar found in Torah Ohr
The struggle between Jacob and an angel is symbolic of the struggle between Good and Evil. Evil has no independent life and exists by living off the scraps, as it were, of the G-dly life-force channeled to Good, how could Evil could struggle for supremacy with Good at all: this should be impossible?
The answer in that G-d transcends any distinction between Good and Evil. G-d could just as easily have created a world in which what we know as Evil is superior to what we know as Good. Evil sought not merely to challenge Good, but to challenge the very Divine plan by which Good is superior to Evil in the first place.
