We develop habitual patterns of relating to our body and the world in an egotistical way. That relationship becomes so solid that we actually become martyrs to the common cold. According to the Buddhist tradition, the excellent means of not corrupting one's basic health is the practice of being mindful. Mindfulness is based on working with the psychosomatic body. They're not separate, yet we live in a world of separation because we haven't synchronized mind and body together.
Mindfulness means mind is full, therefore it includes everything.
Nothing is left out, nothing is discarded. It's a simple, direct situation. We become much clearer about how we think, how we act, how we are sensitive to the environment. The practice of mindfulness works directly with the psychosomatic body, the interpretive factor of mind. The practice of mindfulness is the reminder of basic health, basic well-being.
