There are many elements which make the High Holy Days a unique experience. Often, congregations swell to double or triple their usual size, the musical settings of even common liturgy are different, and some might alter their dress by wearing either traditionally all-white garments or more formal wear than they would sport on Shabbat. Some congregations even have unique garments to dress their Torah scrolls in white.
We read in Pirkei Avot, “Be among the disciples of Aaron – seek peace and pursue it.” One of our highest aspirations as Jews is to establish peace within our homes, within our communities, and in our world. Sh'lom bayit (peace in the home) is a core value of Jewish life.
