Ever since we are born i.e. coming out of our mother’s womb, we are moving towards one imminent end – death. Whatever we are able to accomplish is between these two states. Then how is it possible that we die and take birth every day?
As you think so you become is a mantra enunciated by Krishna in the Gita. We are nothing but a result of our thoughts and convictions and subsequent actions. We do what our mind says and heart desires. So the need is to train the mind or heart and not your actions. As a joint effort, both will take care of the actions!!
