One day, at Barnes and Noble, I discovered a book by Rodney Yee called "Moving Toward Balance: 8 Weeks of Yoga with Rodney Yee". I discovered what a truly amazing teacher he is, and have been inspired in my practice by the care and mindfulness that he shows in his books and workouts.
Last night I did a yoga headstand for the first time. When I first began attempting the headstand, 5 months ago, I never ever thought I'd get to the point where I could do such a difficult (for a 50-something post-cancer woman) pose. I discovered that the yoga headstand doesn't come from the development of external muscles, it comes from an internal sense of balance and relaxation, and from a deep sensitivity to my body that is slowly beginning to come to me from doing 1 1/2 to 2 hours of yoga every night.
