Happiness is within everyone, but we are not able to experience it because of our ego's likes and dislikes.
We live in a calculative world and have a calculative mind, and in such a world, ego dominates.
We human beings are born in ego, live in ego, are brought up in ego and will die in ego. We need a certain degree 0f vision when we live in this world for achieving and attaining our goals in life.
