Buddha taught us to renounce our attachment to our bodies. Our bodies are like ships helping us cross the ocean of suffering to the shores of everlasting peace, Enlightenment. Once we arrive, we discard them, so strong attachment can not be justified.
What does this teaching mean to you? Does it mean giving up cosmetics and going to the gym or spa? At the other extreme does it mean sacrificing yourself to feed a hungry tiger the way the Buddha did? What if your boss asks you to work 80 hrs a week because your store is understaffed? What if you are a policeman? What if your daughter begs you to carry her, and you might hurt your back because she’s too heavy, do you do it anyway?
Meditation subject: the antidote to physical attachment — the mindfulness of the body. Strip off each layer beginning with the skin then the blood vessels, and so forth down to the bone marrow.
