“Extreme attachment to sensual pleasures, in short, is like constantly drinking salt water: with no satisfaction, you’re always in torment, so what chance of happiness is there in it? Since the elephant, mind, is hopelessly drunk with the maddening liquor of sensual desire, there’s minimal chance of taming it with the soothing hook of the holy Dharma.”
