When we sit in meditation and attend to the physical sensations or feelings of the body, we can observe not only relatively exterior sensations like those of the skin or superficial muscles, but we can in our stillness become deeply aware of the function of the organs. One of the easiest to begin to get a feel for is the heart. As become quieter and quieter, we can actually feel the heart beating deep within. When we can understand how the heart functions, very clearly, we can become so sensitive in our ability to feel it, that we could detect any troubles long before stronger, painful sensations might send us to a doctor. Meditation is good preventative medicine!
