The gemara (Succah 5) states that the Shechinah never descends below ten tefachim.
However, Hashem makes sure that no Jew will be detached from Him.
So, during the miracle of Chanukah, Hashem kiveyachol comes down below ten tefachim.
He comes close to man to bring him back up to Him.
~ The Meor Einayim
