The Maid's Sons and the Tzaddik
Rachel gave Bilhah to Yaakov so that the names of the lower levels would come from the maid, then named her own son Yosef, the tzaddik who brings those levels back.
The Noam Elimelech teaches that the Imahos knew twelve tribes would come from them, and that the names of the tribes would hint at every level in the Jewish people. Leah's first four sons stood for four levels of tzaddikim. Rachel knew that opposite them there would be lower levels too, and she feared that the names hinting at them would fall to her own sons. So she gave her maid Bilhah to Yaakov. Bilhah's first son she called Dan, from din, judgment, for people whose mouths are full of harsh words; the second Naftali, read as nofes li, "the honey is mine", for those who keep the world's sweetness for themselves. Then she named her own son Yosef: he would gather away that disgrace. When the Torah says that Yosef was a lad with the sons of Bilhah, it means that the tzaddik brings these lowly people back to the good and leads them into holiness.

Each of us carries something of Dan and Naftali: a sharp word that comes too easily, or a wish to keep the sweet things for ourselves. The Noam Elimelech teaches that the tzaddik's task is to bring such people back, not to push them away. This week, pick one of these two traits that you recognize in yourself. Bring it to a Rav or mentor you trust and ask for one practical step. Then take that step for seven days.
