Years ago, I taught pole dancing (it's exercise!) in a lovely studio in Los Angeles. One of the things I loved most about it was the lack of mirrors. No mirrors anywhere. It was a nice change to have a work out environment where you weren't constantly looking at your own image and judging yourself. Because after all, most people who exercise are trying to improve something they are unhappy about and a mirror is essentially just a magnifying glass on that one part.
I remember being in an aerobics class once where I was so focused on harshly judging my own jiggle, that I hadn't realized that the routine had moved on. I saw it in the classes I taught as well. Women who were beyond beautiful (some of them celebrities) but could not really let go and enjoy the class for fear of being judged for their own perceived flaws.
But over time, the girls taking the class, as well as myself teaching it, we learned to rely more on how we felt about ourselves as opposed to what we thought we saw in the mirror, which of course is what we fear others will see too.
I was most moved by a woman who had endured a mastectomy and several painful followup surgeries to repair scar tissue. After three months of classes, she wore a low cut t-shirt for the first time since the operation. She told me it was the first time since that she felt brave. It was the first time she felt beautiful.
Once you leave the mirrors and thought about body image behind, you are left with how you feel on the inside. Your essence. Your spirit. And in that, you are brave and you are beautiful.
Now I'm not completely disrespecting the mirror. Of course, mirrors are very useful for finding out if you have spinach in your teeth or if your dress hem is caught in your kickers. But never let them tell you who is fairest of them all.
