In order to be happy, you should love - love with self sacrifice, love all and everything, and spread a network of love everywhere. No matter who gets into this net, catch them all and fill them with love. Everyone can recall a moment, universal to all, perhaps from early childhood, when you wanted to love everyone and everything - your father, your mother, your brothers, evil people, a dog, a cat, grass - and you wanted everyone to feel good, everyone to feel happy; and even more, you wanted to do something special so that everyone would be happy, even to sacrifice yourself, to give your life so that everyone should feel happy and joyful. This feeling is the feeling of love, and it must be returned to, for it is the life of every person.
