"What goes around comes around."
"You reap what you sow."
"For every action there is an equal and opposite reaction."
Karma means action, work or deed. Good intent and good deed contribute to good karma and future happiness, while bad intent and bad deed contribute to bad karma and future suffering. The law of karma states that for every action, there is a corresponding effect. It is the continuous process and involves the past, present, and future. It is the affect of your actions. Can be good or bad. Karma is not about punishment or reward. It makes a person responsible for their own life, and how they treat other people.
Karma is the universal principle of cause and effect. Our actions, both good and bad, come back to us in the future, helping us to learn from life’s lessons and become better people. Karma is the best teacher, forcing people to face the consequences of their actions and thus improve and refine their behavior, or suffer if they do not. Karma is powerful. Don't hurt anyone. Be good do good.
