"I tell myself: reluctance to think to the end Is lifesaving for the living. Could lucid consciousness Bear everything that in every minute, Simultaneously, occurs on the earth? Not to harm. Stop eating fish and meat. Let oneself be castrated, like Tiny, a cat innocent Of the drownings of kittens every day in our city. The Cathari were right: Avoid the sin of conception (For either you kill your seed and will be tormented by conscience Or you will be responsible for a life of pain)."
