Torah 72: Rabeinu explains that when a person has a thought of returning to G-d and immoderately follows that thought with a holy act, for example to go to the tzadik, the closer he gets to the tzadik the more he loses his initial desire. This is because he broke his initial yetzer hara and now has a completely new one. Rabeinu tells us that we need to break this new yetzer hara and overpower it with a new desire, to reinforce ourselves against this new evil inclination.

Rabeinu goes into depth about the different levels of the evil inclination and advice on how to defeat the evil inclination of your own level.
