Let the honor of your friend be as dear to you as your own.
“They Rabbi Eliezer said: Let the honor of your friend be as dear to you as your own; and be not easily provoked to anger; and repent one day before your death. And [he also said:] warm yourself before the fire of the wise, but beware of being singed by their glowing coals, for their bite is the bite of a fox, and their sting is the sting of a scorpion, and their hiss is the hiss of a serpent, and all their words are like coals of fire.”
Tractate of Avot 2:10
We should always treat our neighbors in the manner we would expect to be treated. Restraint and moderation are of utmost importance. Every person must search for the hidden light and not fear the unknown. We must always repent, even on the day before we die. Though no one knows when they will die, improvement and repair are constant options. We must therefore repent as soon as we can. Moreover, while we should honor our sages and revel in their light, we should be wary of becoming too close to them, as they may inflict damage in their time of anger. Higher spiritual levels are not easily attained and we should therefore be cautious about our progress and make slow advances.
Moderation is using humility to make behavioral choices.
