1. One must concentrate when fulfilling the commandment of dwelling in the Sukkah that it is a reminder of the exodus from Egypt, and also of the clouds of glory in which Hashem placed us in the desert. When a person makes the blessing “Leishev” he should intend to use it for the entire meal, and any sleeping or any other activity he will perform in the Sukkah until the next time that he makes the blessing. In the blessing of “Shehecheyanu” that one makes on the first night he should have in mind the festival itself as well as the Succah.
2. A proper formal eating, obligates the person to eat in the Succah. However, a snack may be eaten outside the Sukkah. Regarding sleeping, however, even a short nap obligates the use of the Sukkah.
