Our Gemara on Amud Aleph discusses the halakhic requirement that a Succah must be a temporary dwelling. The commentary of Bas Ayin (Succah 11) written by Rabbi Dov Me-Abritch (1760-1840) offers a symbolic interpretation of this halakha, similar in style to what we have been studying the past few daf.
The temporary nature of the Succah reminds us that even when we reach spiritual heights they are difficult to hold onto, and necessarily temporary. The Rambam in his introduction to the Moreh Nevukhim discusses spiritual insight With the following metaphor: a person could be walking in the pitch dark and suddenly a lightning bolt that lights up the sky momentarily. From that momentary burst of light one gets a picture of the entire terrain and it could help them throughout the night. There are some who are fortunate and experience several lightning bolts throughout the night, but others only experience it only once. Such is the way with spiritual insight.
