Seven is an important number in Judaism. The seventh day, for example, is Shabbat—the holiest day. The menorah in the Holy Temple in Jerusalem and seven candles and there are seven “candles” of the human head (two eyes, ears and nostrils and one mouth.) There are the seven days of mourning and the sheva brachot, the seven blessings and celebrations of marriage.
In Likutey Moharan, Lesson 21, Rebbe Nachman weaves a complex tapestry including several of these seven-related concepts, each one of which offers us rich insights into personal change and the growth of our soul, and challenges us to see ourselves in unexpected ways.
