Likutei Moharan 27:8/ליקוטי מוהר"ן כ״ז:ח׳

18. <Thus when a person achieves the aspect of a radiant and majestic countenance, he merits a refined voice, as above. And with a refined voice, he merits “peace> in his body” so that none of the four humors overpowers any of the others; “peace in his money” so that this one does not come and devour the other, as in the words of Nakdimon ben Guryon’s daughter (Ketuvot 66b) ; “peace in his Torah,” free of any conundrums. As a result, “Yaakov arrived whole in the city of Shekhem.”
