“You have nothing and you would give me a world. I owe you a world.”

Context: People are taking the piss out of you every day. They butt into your life, take a cheap shot at you and then disappear. They leer at you from tall buildings and make you feel small. They make flippant comments from buses that imply you’re not sexy enough and that all the fun is happening somewhere else. They are on TV making your girlfriend feel inadequate. They have access to the most sophisticated technology the world has ever seen and they bully you with it. They are The Advertisers and they are laughing at you. You, however, are forbidden to touch them. Trademarks, intellectual property rights and copyright law mean advertisers can say what they like wherever they like with total impunity. Fuck that. Any advert in a public space that gives you no choice whether you see it or not is yours. It’s yours to take, re-arrange and re-use. You can do whatever you like with it. Asking for permission is like asking to keep a rock someone just threw at your head. You owe the companies nothing. Less than nothing, you especially don't owe them any courtesy. They owe you. They have re-arranged the world to put themselves in front of you. They never asked for your permission, don't even start asking for theirs.

Se puede no deber nada devolviendo la luz al sol.

Context: I say: "What you give, you give to yourself; what you do not give, you give up." And this is to say that whatever you do in the world, you do to yourself; and whatever you do not give to the world, you lose. If I keep my knowledge, I lose it. (...) One receives knowledge and gives it. When you give knowledge, you enrich yourself. If you do not give love, you are detracting from yourself. If I begin to help people, if I begin to heal people, I begin to heal. Do you understand? To be a therapist, you have to be a patient. The first thing to do to heal yourself is to heal others. I have one more saying: "I do not want anything for myself that I do not want for others".
