Everyone, practically, they are not serving any boss or any master, they are serving their senses. Suppose if I am serving somebody as my boss, actually I am not serving his money..., serving his person. [If] I am serving his money. If he says, "Tomorrow you have to work free. You are getting twenty dollars a day now. Tomorrow I have no money. You will have to work free." "Ah, no, no, sir. I'm not coming because I am not serving you; I am serving your money." So actually we are serving money. Any why you are serving money? Because with the money we can satisfy our senses. Without money, we cannot satisfy our, these informidable senses. If I want to drink, if I want to enjoy such and such things, then I require money. Therefore ultimately I am serving my senses.
