GEN579 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.
