Bataille's On Nietzsche

I’m a fourth year contemporary political theory class and have been asked to read Bataille’s On Nietzsche. I am having difficulty, can anyone help me with following concepts.

Immanence
Summit
Chance
Evil
Nothingness
Desire

I understand that work generally about the decline of communication after the death of god and its comprehensive system signifies pointing upwards. However, the work is interesting yet at times incomprehensible.
