Eat To Live, Don't Live To Eat - Prabhupada 0306
Just like you have to eat. That is the demand of your body. But don't manufacture varieties of menus. Eat only to live, not to live to eat. They have made it a point not to eat for living, but they're living for eating. Therefore Bhāgavata says, kāmasya nendriya-prītir (SB 1.2.10). Our indriya-prītir, our sense gratification, is eating, sleeping, sex life and defending. That is our indriya-prītir. So Bhāgavata says, "Yes, you're allowed to satisfy your senses so that you can keep fit yourself to execute higher procedure of life." And what is that higher procedure of life? That higher procedure of life is jīvasya tattva-jijñāsā. That tattva-jijñāsā, "What I am?" For this purpose you shall eat, you shall sleep, you shall satisfy your senses, you should defend yourself—to fulfill this mission of life, to understand what I am. Otherwise the animals are also doing that.
