As I have already said, the child enquires, "What is this, father?" Similarly, we should also enquire, "What is the origin of this universe?" Not only universe, but any item within our experience, naturally we are inclined... Just like here is a microphone. So an intelligent person is inquisitive to enquire, "Who is the manufacturer of this microphone?" Just like we enquire about a child, "Whose son he is? Who is his father?" similarly, this is human mind, to enquire about the origin. That is the only business of human being.
