We, the living entities, are meant for enjoyment, but we are seeking enjoyment in a false place — in an illusion. We are like the desert animals who run after water in a mirage and eventually die of thirst. They cannot relieve their thirst with such illusory water. Similarly, we are trying to manufacture many things to satisfy our thirst for enjoyment, but we are being baffled at every turn because material existence is an illusion. Therefore real intelligence means to inquire, “Where is the reality? Where is the eternal substance behind the illusion?” If we can find that out, we can experience real enjoyment.
