Peace is the greatest attribute of all, for we are not told to pursue any other mitzvah but rather to fulfill them when the opportunity arises, such as "If, along the road, you chance upon a bird’s nest", "When you encounter your enemy’s ox or ass wandering" or "When you see the ass of your enemy". Whereas concerning peace, it says "seek peace and pursue it", to go from place to place to make peace. This is what the Tanah means in Pirkei Avot: "Be of the disciples of Aharon, loving peace and pursuing peace". The meaning is that it does not suffice to love peace when it happens to come by, but that you should also pursue peace, even when it does not happen to come by. This is how, with Heaven's help, I say we are to explain what our Sages, of blessed memory, have said: "Torah scholars increase peace in the world". To be precise, what do "increase" and "in the world" mean? They could have said that Torah scholars make peace, but the text makes it clear that, aside from making peace, they also increase it by pursuing it, in the world, wherever it is necessary to make peace."
