How material enjoyment increases our suffering
The body must be considered a diseased condition. A diseased man cannot enjoy himself properly; a man with jaundice, for instance, will taste sugar candy as bitter, but a healthy man can taste its sweetness. In either case, the sugar candy is the same, but according to our condition it tastes different. Unless we are cured of this diseased conception of bodily life, we cannot taste the sweetness of spiritual life. Indeed, it will taste bitter to us. At the same time, by increasing our enjoyment of material life, we are further complicating our diseased condition. A typhoid patient cannot eat solid food, and if someone gives it to him to enjoy, and he eats it, he is further complicating his malady and is endangering his life. If we really want freedom from the miseries of material existence, we must minimize our bodily demands and pleasures.
