He who loves his neighbor burns his heart, and the heart, like green wood, groans when it burns, and distills itself in tears. There is no point in taking opium; it is better to put salt and vinegar in the soul's wound, for if you fall asleep and no longer feel the pain, then you no longer exist. And the point is to exist.
