If you are not selfish you will not be altruistic, remember. If you are not selfish you will not be unselfish, remember. Only a very deeply selfish person can be unselfish. But this has to be understood because it looks like a paradox.
What is the meaning of being selfish? The first basic thing is to be self-centered. The second basic thing is always to look for one’s blissfulness. If you are self-centered, you will be selfish whatsoever you do. You may go and serve people but you will do it only because you enjoy it, because you love doing it, you feel happy and blissful doing it—you feel yourself doing it. You are not doing any duty; you are not serving humanity. You are not a great martyr; you are not sacrificing. These are all nonsensical terms. You are simply being happy in your own way—it feels good to you. You go to the hospital and serve the ill people there, or you go to the poor and serve them, but you love it. It is how you grow. Deep down you feel blissful and silent, happy about yourself.
