A bundle unifies and embraces its components, and God is whole and embraces all. It is on this point of similarity that the Divine Presence accompanies a group of five people who occupy themselves with the Torah. Not only do these ten constitute a public fulfillment of the mitzvah, but they create a new reality, the reality of a 'tzibbur,' a community. Thus, the strength of the people is incomparably greater than the combined capabilities of all its members. Every individual can reveal Godliness in his Torah learning, but the light revealed by communal Torah study comes from a higher source, beyond any limitation.
Hatred stirs up strife, but love covers all sins.
Too much talk leads to unavoidable sin, he who restrains his lips is wise. A refined Jewish soul should be careful to avoid idle chatter, since even this consumes a large part of a person's life and fritters away his time. . . . Just as with a telegram, ultimately a person is held accountable for every word. If one is compelled to speak, he should deliberate whether his words are among the forbidden forms of speech. In summary, one must be a superior guard in G-d's vineyard.
