Consider your models. Yoga is a great practice to train the minds’ attention in cooperation with embodied activity, but the how and the why of the activity are important too. The mindfulness purpose of yoga that exists as it was originally practiced in eastern cultures has been distorted for the purposes of exercise or a dieting tool or increasing flexibility.

This, for example, doesn’t look healthy to me.

Seriously honor the integrity of your spine’s natural counterbalancing curves. When you stand do you tip your head back like that looking at the sky?  The handstand serves the purpose to put your vertical alignment into gravity in a new way so you must attend to the trueness of that verticality. This means don’t look to the ground. Look forward…just like you do everyday of your life. Why should it be any different when life is turned upside down?
