Yesterday I forgot the pair of glasses or contacts that I normally practice yoga with. I have very little visual acuity without corrective lens' and thought it would be kind of liberating to feel and practice my way through class - hot class.
Although I've done this before a couple of times, yesterday I was very mistaken. During the first 15 minutes I discovered that I am already spatially self aware however without corrective lenses and both feet on the ground I am vulnerable to fall. I became terrified, frustrated and felt a lot of self pity. I found that without the sense of sight my mind became very chatty and defeatist.
I needed to get control of my emotions quickly because it was unnecessary to feel all those emotions. It wasn't helping me practice.
How would I practice if I were blind? Simple. Just keep practicing. This video is some pretty intense inspiration.
