Darn it...I pretty much wasted my yoga class last night.
The instructor was excellent and very encouraging:
"Let the cadence of your breathing allow every muscle in your body to relax"
"Feel all the stress in your body released through your toes and finger tips"
"Just release all your stress from the day, slowly breath in and out, feel the tension releasing"
Only problem was that I had had a bean burrito for lunch earlier in the day and I was afraid to relax all my muscles and sphincters.
