““What is necessary beforehand. – A man who is not willing to become master over his wrath, his gall and a vengefulness, and his lust, and who tries to become master in anything else, is as stupid as the farmer who lays out his field beside a torrential stream without protecting himself from it… This most shortsighted and pernicious way of thinking wants to make the great sources of energy, those wild torrents of the soul that often stream forth so dangerously and overwhelmingly, dry up altogether, instead of taking their power into service and economizing it.””
