What should a person do to ensure pardon and exoneration on Rosh Hashanah and Yom Kippur? One should be with the community, and join with the entire nation, for through unity one benefits from the exoneration of the general public by the Thirteen Principles mentioned in the Torah. As Hosea said, "Ephraim is addicted to images— Let him be", meaning that when the nation of Israel were united, the Holy One, blessed be He, forgives them for everything. This corresponds with what we find in Tractate Yoma: The First Temple was destroyed because of three things it contained – foreign worship, incest and bloodshed. And why was the Second Temple, in which they dealt in Torah, mitzvoth and charity, destroyed? Because of gratuitous hatred. In the first case, the transgressions were exposed, and their end was revealed; the end of the latter, whose transgressions were not exposed, was not revealed. That is, all could see and know of the transgressions during the First Temple and knew why they had been punished. But in the Second Temple, where there was gratuitous hatred – something that remains hidden in the heart and cannot be revealed except to those who with hidden knowledge and to He who sees through the heart and entrails – their end, measure for measure, was not revealed. The remedy for this, therefore, is the reconciliation of hearts, to all be united as one. Even when the commandment to rebuke is called for, one should not do this out of hatred but do so according to "overt rebuke is preferable to hidden love".
