Our Sages, of blessed memory, said: The People of Israel can be credited for having fulfilled all the commandments through unity. Since all are as one – what is fulfilled by one is considered as having been fulfilled by the other, and the benefit bestowed by Torah and the observance mitzvoth thus increases. Through unity, one may rejoice when others benefit, or share in their sorrow. It is the equivalent of fulfilling the entire Torah, since to love one's neighbor as oneself is the greatest principle of Torah, as our Sages, of blessed memory, said, as is fulfilling the commandment to “let him (your kinsperson) live by your side” and sustain them. This way there will be no gratuitous hatred, which was the cause behind the exile, and love will replace enmity, for this is what brings the presence of the Shechina.

Unity also helps pursue the truth, for just as we do not want others to be dishonest with us, so will we avoid being dishonest with others, and just as we are willing to share an privilege or a good thing, so do we wish that others share their privilege and good things with us, and vice versa. Unity also protects us from being one of those who profit from the community for the wrong reasons and take only their personal benefit into account. It helps us consider all the People of Israel as though they children of angels – and to appreciate them as we do ourselves.
