I found this amazing free app on the App store, it's called Epic Breath from Help You Rock Software. If you don't have a ipod, iphone or ipad you can also listen to it online here http://www.totalauthenticity.com/EpicBreath/EpicBreathCleanse.mp3
All you have to do is lay down on your back and follow the breathing instructions. (Pics of the 2 positions below)
"Many say the Breath Cleanse has them vibrating from head to toe. Others testify that the experience led them to the most tangible experience of spiritual energy inside their body. Over 10,000 have experienced this phenomenal breathing experience.
There is an incredibly powerful tool we have that very few of us completely acknowledge and utilize. It is our breath. Without it, we cannot live, and when we really become aware of it…we come alive.
Our breath carries with it much more than oxygen, it carries the elements of life, of energy, and of health.
Epic Breathing is a technique that fills the body with so much oxygen and chi (energy) that you may find yourself feeling weightless, revived, and for many who come with asthma or other chronic ailments, including broken bones – healed.
In Tibet, there are monks who sit in the icy snow, wrapped with a wet towel, and through a meditative breath practice they are able to not only remain warm, but are able to dry the towels. The same technique they use, Tumo Breath, is at the core of Epic Breathing. This is ancient wisdom with modern results."
