A mitzvah is a commandment, but the word has become a synonym for those sublime kind deeds that people do for others. In simple poetic and often humorous prose, Dany Siegel presents a dozen Mitzvah people who are helping to repair the world, whether from collecting pennies to rescuing birds..from picking potatoes to lending wedding gowns. Each story concludes with ways all of us , young and old, can begin to do mitzvahs.
