Jews commemorate the forty-nine day period between Pesach and Shavous by counting each and every day. This important mitzvah teaches us how to make time count. With stories of tzaddikim who used their time wisely, Rabbi Wein illuminates ways we can implement this all-important skill into our own lives. Delving yet deeper, Rabbi Wein examines the meanings of the mystical concepts of the Sefiros, making these esoteric concepts accessible and showing how the period of mourning leads us to the ultimate goal of Shavous, a yom tov of happiness and unity.
