I had the pleasure of going to a retreat in Finland with Dave Oshana. It was a weekend of some of the strongest energy I have ever felt. A combination Satsang practice with Qi Gong that Dave uses to help open up the seeker. You can tell a good teacher when you look in the eyes of the students around him and see their hearts burning through their eyes. He doesn’t have any videos online yet but you can check out his work at Enlightenment-Now.com.
