I've found a site that has a really good e-book on meditation and mindfulness (online and free). The address is http://www.urbandharma.org/udharma4/mpe.html. If you are interested in meditation, this looks like a great resource. Mindfulness is a wonderful meditation technique where you keep the mind completely absorbed by your current situation and activity. You focus your thoughts entirely on the sensations, movements, and emotions evoked in your current state. This book looks like a good place to start if you are interested in this area of meditation.
