"It's not what you look like when you're doing what you're doing... it's what you're doing when you're doing what you're doing."
Now there's a tongue twister! But something worth considering.
What if you applied this to yourself in yoga class? If, instead of focusing on what others may notice about your practice, you focused on your yoga, you'll find your asana transformed.
You'll spend less time looking around the room, and more time in your meditation. And then you can really express yourself.
PS What a joyful video, too!
