On Rosh Hashana all the Jews’ thoughts are united. During the year we are caught up in the earthly world of divisions. On Rosh Hashana we turn our thoughts to Olam Haba (the World to Come), a world of complete unity. Peace treaties are not true peace because the two sides are selfishly motivated. When we all think that we are the G-d, there is no room for G-d. Before the advent of Yom Kippur, we need the bitul hayeish (nullifying our focus on our physical selves) of Rosh Hashana. Most marriage issues can be solved by renewing the couple’s caring relationship.
