Although a sukkah is only a temporary dwelling, in certain respects, we treat it as if it were our regular home – eating, drinking and studying Torah in it.  This, too, is the way we should treat the world at large.

We should not regard the world as an end unto itself, but rather as a means of furthering our spiritual development and refinement. 

By properly utilizing the physical word, and making the most of it in a spiritual manner, we bring G-dliness into our surroundings, transforming the temporary into something lasting and eternal.

~ The Lubavitcher Rebbe zt”l
