Karma plays a significant role in everything and everybody's life. All that you are facing today is a result of your Karma. You can say that it exists to make us aware of the cyclic pattern of our lives and how no event, no relationship, nothing is a coincidence. Start by practising kindness, compassion and generosity in your life. Karma says that whatever you do, you will become. So, keep this thought in your mind, and start doing good to others without expecting to get something in return.
