Why It's a Mitzvah to Sleep

Although he may not feel it, every journey in a Jew’s life is ordained by his Creator and part of his Godly mission.

This is true even when it seems to a person that he is being inactive. After all, we read in the Torah that when our ancestors travelled through the desert, it was “at G-d’s command that they journeyed” and it was “at G-d’s command that they encamped.”

Even when at rest, a Jew is actively performing G-d’s mission. The key is to be aware of it.
