Interesting title from Richard Freeman (mind you, he is always interesting). Before you jump to conclusions watch the video Yoga ruins your life...  as you once knew it.

This video is just fabulous-Thank you to the person who posted it. How wonderful to have all this information, from all these amazing first generation Ashtangi-So much shared knowledge and wisdom and not an asana in sight. 

The Basics of Pranayama Yoga with Richard Freeman. I found this a really interesting clip on pranayama. Richard touches briefly on Mula bandha too (very briefly, but quite specifically). He seems like quite a chracter. Enjoy!
