Chazal tell us that the Divine Presence does not descend lower than ten tefachim from the ground.  The only exception to this is the menorah on Chanukah, whose place is ideally required to be less than ten tefachim off the ground.  The shechinah, on this occasion, does descend lower than ten.  This is the mystical concept that lies at the root of the Gemara that says: If your wife is short, bend over and whisper to her. ~ R’ Dovid of Tolna zt”l
