Between Man And His Fellow-Man

As soon as there rises from the beinoni's heart to his mind any animosity or hatred, G-d forbid, or jealousy, anger or a grudge, and their like, he will bar them from his mind and will. On the contrary, his mind will prevail over and dominate the feelings of his heart, to do the exact opposite namely, to conduct himself toward his fellow with the quality of chesed and to display towards his fellow a disproportionate love, in suffering from him to the furthest extreme, without being provoked into anger.

(Baal HaTanya)
