Musar sobre Malaquías 1:2

And this is the intent of the verse "You shall not take revenge and you shall not bear a grudge against the sons of your people. And you shall love your friend as yourself — I am the L-rd." If you say: "How can I make myself not have anything against him and even love him?" the verse itself provides the answer — "I am the L-rd." As per (Malachi 1:2): "'I have loved you,' said the L-rd," and (Devarim 14:1): "You are sons to the L-rd your G-d" — you, too, can love him. And, in truth, the matter is simple. For since a man looks "downwards" at his friend, seeing him clothed in physical matter, he [his friend] is not very significant to him, especially, if he is against him in some matter, in which instance he "nullifies" him completely. Not so the Holy One Blessed be He, who knows, in essence, that the root of the holiness of the soul of Israel is exceedingly great and awesome, as it is written in the holy Zohar in several places, that the root of the holiness of the soul of Israel on high is in an extremely awesome sphere, wherefore their eminence and His love for them, accordingly, are extremely great.]
