A few weeks ago, as I settled into an exceptionally crowded midday class, a young, fairly heavy black woman put her mat down directly behind mine. It appeared she had never set foot in a yoga studio -- she was glancing around anxiously, adjusting her clothes, looking wide-eyed and nervous. Within the first few minutes of gentle warm-up stretches, I saw the fear in her eyes snowball, turning into panic and then despair. Before we made it into our first downward dog, she had crouched down on her elbows and knees, head lowered close to the ground, trapped and vulnerable. She stayed there, staring, for the rest of the class.

Because I was directly in front of her, I had no choice but to look straight at her every time my head was upside down (roughly once a minute). I've seen people freeze or give up in yoga classes many times, and it's a sad thing, but as a student there's nothing you can do about it. At that moment, though, I found it impossible to stop thinking about this woman. Even when I wasn't positioned to stare directly at her, I knew she was still staring directly at me. Over the course of the next hour, I watched as her despair turned into resentment and then contempt. I felt it all directed toward me and my body.
