The entire Torah and all the mitzvos are called 613, taryag eitzos, solutions for coming close to Hakadosh Baruch Hu (Zohar HaKadosh). The next time a person encounters a nisayon, he won’t be tempted too much, because he will refuse to part with that feeling of kirvas Elokim. He has already experienced the taste of holiness, of Shabbos, of true thoughts of teshuvah. He has already shed tears of emotion from closeness to Hashem. He doesn’t want to give this up!
This is what the Ribbono shel Olam wants—that the Torah should cleanse us so thoroughly that we feel that the greatest thing we can lose is our kirvas Elokim. This person will think to himself, “Even if I can find a leniency to do what I want, I may lose my taste in Shabbos... I may lose my kirvas Elokim.”
