Torah 261 · תורה רס״א

When a person falls from his spiritual level, he should know that it is Divinely ordained. This is because being rebuffed is the beginning of being drawn close. He therefore fell, in order that he should motivate himself to draw closer to God.

The advice for him is to start anew, to enter the service of God as if he had never begun before. This is a very important rule in the service of God: Literally every day, people need to begin anew. {See more on this subject elsewhere in the works of Rabbeinu z’l; how important it is that a person strengthen himself in the service of God and not become discouraged because of anything in the world, but rather always start anew. Study this subject well, and it will be forever pleasing to you.}
