I found this site online yesterday: http://www.yogijim.com/
It offers free downloads of yoga and meditation. I found them to be less yoga, and more kind of guided meditation, but there is a large selection for a variety of needs: addictions, self-soothing, etc.
You can also check out
The Big List of Free Guided Meditations. I created the list including guided meditation videos and audio ranging from 3 to 30 minutes in length on varied topics including guided meditation for children, cosmic meditation, meditation for more energy, better sleep, eating less, and more. I'd love to know what you think of them and which ones you enjoyed most. Please leave me feedback as I constantly update the Big List!
