There are many theories around the theory of Karma. A lot of us believe that our present actions are the outcome of our past actions. That means we have no control over them for any improvement.
But Karma determines only our experiences and not our actions. Our personal happiness and sorrow is the result of our past actions but what we are doing at present is not the result of past actions. There is a tendency sometimes to blame Karma for our decisions. Secondly, Karma is very empowering. We wrongly understand that we have no choice in life that is bound by our Karma. Basically, Karma gets mistaken for fate or destiny, which it is not the case.
If work is Karma, its effect is Karama-phala or fruit of work. It is difficult to deny that actions have consequences. Everything that we do has results. Secondly, it is difficult to deny that we all want our life to be happy, meaningful and fulfilling. Thirdly, it makes difficult to deny that our hope for justice for life makes it difficult to oversee that goodness is rewarded and evil punished. That is what Karma theory in the essence is. There is no need to blame anyone for our sorrow or be indebted to anyone for our happiness. We are responsible for both for our action as well as the results of our actions.
We rarely question the existence of happiness in our life. If something makes us happy, we say we deserve it. Only when there is failure, then we ask, “why me”. The general tendency is to find an external cause for the trouble and blame it. Then the control as to when I should be happy or unhappy depends on others. Then there is no freedom to be happy.
It is inevitable that some news or happening will make some of us happy and some others unhappy. Should I be overwhelmed by the joys and sorrows in life? Both can be overwhelming. If we are getting overwhelmed by joys or sorrows, then the clarity of our mind is lost.
