Without intention, all these postures, these breathing practices, meditations, and the like can become little more than ineffectual gestures. When animated by intention, however, the simplest movement, the briefest meditation, and the contents of one breath cycle are made potent.

One study on the treatment of asthma patients conducted by researchers John Goyeche, Dr. Ago, and Dr. Ikemi, suggests that any effective treatment should address suppressed emotions-such as anxiety and self-image-as well as the physical dimension. To achieve this, they encourage correction of poor posture, and helping the person relax the irrelevant respiratory muscles while restoring full diaphragmatic breathing. They also recommended finding ways for getting rid of excess mucus. The good news is that a well rounded breath practice will do all these things.

The process of breathing is the most accurate metaphor we have for the way that we personally approach life, how we live our lives, and how we react to the inevitable changes that life brings us.

What yoga philosophy and all the great Buddhist teachings tells us is that solidity is a creation of the ordinary mind and that there never was anything permanent to begin with that we could hold on to. Life would be much easier and substantially less painful if we lived with the knowledge of impermanence as the only constant.

Life is not inherently meaningful. We make meaning happen through the attention and care we express through our actions.

Yoga does not remove us from the reality or responsibilities of everyday life but rather places our feet firmly and resolutely in the practical ground of experience. We don't transcend our lives; we return to the life we left behind in the hopes of something better.

The asanas are useful maps to explore yourself, but they are not the territory.
