Regarding the first night of Shavuos, the Arizal writes “Know that one who does not sleep at all this night, but instead spends all his time learning Torah, is guaranteed that he will live out the year and no harm will befall him.”
This year, with Shabbos preceding Shavuos, it is a wonderful opportunity to take a nap and be better equipped to learn the entire night. This statement and guarantee by the Arizal should not be taken lightly. But in order to get this guarantee, a person has to spend “all his time learning Torah,” – which probably means without taking a break and talking to friends. We are all capable of this. If you try to do this, Hashem will assist you and make it happen. Haztlocha!
