The person who sins will die. A son will not be punished for his father's sins, and a father will not be punished for his son's sins. The righteousness of the righteous person will be his own, and the wickedness of the wicked person will be his own. - Ezekiel 18:20

How true these words are!

Every life is a separate entity. Everyone is responsible for his or her own karma. There is no one to blame or give credit. One's karma is his or her own equity. It cannot be divided or shared.
