The body is the least of you. The body matters to you considerably, yet the body, this shell around you, is irrelevant. Yes, take care of it. Nourish it, and yet not be attached to it. Physical bodies on Earth have become all important. The material cries out to you: "Keep us! Keep us at all costs. Keep us as if nothing else matters." All the while, there are matters that matter far more than the body, what it looks like, how it feels, how long it lasts and so forth.
