Since times infinite, humans have been trying to know the reality of this world, but they haven't yet known the truth. What actually has to be known is that Who am I, Who runs this world, and Who created this world. Usually, if something good happens then one takes the doer ship, whereas if something bad happens then one starts to blame God or his own unfavorable stars. All these are wrong beliefs. God is not prejudiced that he will make you suffer. Who runs the world? There is no independent doer in this world. Scientific circumstantial evidences are the doer. But due to ignorance, one lives in the illusion of egoism that he is the doer. Who created this world? Why there is unhappiness in this world? Is there justice in this world? Who runs the world? Who is the doer? In this compilation, Param Pujya Dada Bhagwan has given a very simple and direct understanding of all these questions and revealed the mystery behind doer ship.
