GEN582 The deeds of the righteous may be compared to children.  Just as children keep the memory of their parents alive by continuing the work and values of their parents, so, too, the actions of the righteous continue to have impact long after they are gone physically.  (Rashi).  AMEMEI 53, 234, 298.  Similarly, philanthropists who have helped Jewish education and Jewish poor have begun projects whose effects will be felt for hundreds of years to come.  AMEMEI 189  Moreover, immortality can be achieved by doing righteous acts that affect people.  The impact of these acts continues long after the person dies physically.  Chofetz Chaim enhances this concept when he says that one strong act of kindness can impact not only one person, but can continue to have impact from generation to generation until the end of time.  Shemirat HaLoashon 1:7.  .  Therefore, by being good, a person has the potential to affect thousands or even tens of thousands of individuals for the better and change the world positively forever.  AMJV 159.
