The black locks of hair hang down the sides, covering the ears. This is, we learned, the meaning of the verse, “Hashem bend your ears and hear” (II Melachim 19:16). We have deduced from this that whoever wishes for the king to bend his ear towards him should curl the king’s hair, that is, aim to adjust the judgments deriving from the hairs on the head of Zeir Anpin and pull back the hair from over the ears so it will not hinder the hearing of prayer. Then the king will listen to all that he requires.
