One of the best ways to practice preserving kindness is to create an ethical will. Writing an ethical will is a centuries-old Jewish practice that is making a comeback among Jews and others. Originally an oral tradition, with parents passing on their values, blessings, life lessons, and forgiveness to their children, ethical wills have been committed to writing for the past one thousand years.
