Yesterday at the William Penn House class, we were emphasizing strong working of our tailbones. One of the regular students came to class even though she was still exhausted from recent and sudden major loss and upheaval in her life. She wanted to be with the spirit of the class even if she would not be able to do everything.
When we went to the wall to work on half and full arm balance, I advised her to give it a try if she felt up to it and then said to do legs up the wall if she knew trying to hold the arm balance would be too much. After all, I pointed out, legs up the wall (vipariti karani) is just half handstand upside down. And what is awesome about both the poses is that the both turn us upside down (albeit in energetically different ways) and can thus help give us a fresh perspective on how we are in our bodies and minds.
