"If there is an action, there will be an equal but opposite reaction."

This is related to the Law of Cause and Effect in Buddhism.

Karma means your deeds, whether good or bad in life. Whatever you do, -good or bad is your Karma. Good Karma will be blessed with Good & Bad Karma will be repaid with Bad..... Whatever you do will be repaid, if not in this life, may be in your next one.

In the cycle of birth and rebirths be bring all karmas of our previous life along. To know your past life, look at what you are today. To preview your next (future) life, look at what you do today.
