Marbeh Lisaper on Pesach Haggadah, Maror 1:1
(1) Maror Korekh: Even if some disagreement or bitterness burns in his heart, let him ‘wrap up’ (hikhrikh) any hurts with love and let him judge all people favorably, as we learn in Masekhet Shabbat: “Our Rabbis taught: He who judges his neighbor in the scale of merit is himself judged favorably,” and elsewhere in the Talmud. The sages of blessed memory also quote the following verse: “Better to be forbearing than mighty; to have self control than to conquer a city.” There are those who remain calm even when their body is aching, a fire is burning in them and bitterness is dripping within them – such people are subject to terrible diseases. Others, however, remain completely calm and do not allow their hearts to become angry. This is a great quality – greater than conquering a city.
