“It’s like a dog. If you feed it plain rice every day, it’ll get fat like a pig. But if one day you start mixing some curry in with the rice, just one or two meals, then after that if you give it plain rice again, it won’t eat it. It gets addicted to the curry really fast. Sights, sounds, smells, and tastes are things that can destroy our practice. If we don’t contemplate our four requisites—clothing, food, shelter, and medicine—Buddhism won’t be able to survive.”
