Wherever our feet tread, it is all in order to cleanse and purify the world with words of Torah and prayer. We, all of Israel, are emissaries of G-d, each of us as Divine Providence has decreed for us. None of us is free from this sacred task placed on our shoulders.
Rabbi Yosef Yitzchak of Lubavitch (Hayom Yom, 5 Adar I)
