#It’s important to learn at night and not waste it all with sleep, eating, and talking because one accomplishes most of his learning at night <ref> Rambam (Talmud Torah 3:13)</ref>, that learning is not easily forgotten and is considered like the Avoda of the Korbanot. The joy of Torah is specifically felt for learning at night and Hashem grants a special Chesed for one who learns at night. <ref>Avoda Zara 3b </ref>.
