For the month of September, I chose the Revolved Praying Hero posture. In the more fitness oriented postural yoga, this one is also known as Revolved Lunge. The technical or Sanskrit name of this posture is Parivritta Namaskara Virasana. I deliberately do not use sanskrit terminology during yoga classes, because that is like giving a Catholic mass in Latin. And that is no longer of this time.
Sanskrit is good for the technical classification of postures or if you are studying or retraining in the Indian tradition.

Why does this posture fit so well with the month of September?

This posture fits well in this transitional season between summer and autumn. It is a yoga posture with a strong “grounding” character. Still, it is also “fiery”. It is a posture in which the earth element comes to the fore and the fire energy of summer can still be felt. It invites you to stand firm and stay in balance. That is exactly what we have to do now.
In the transitional periods between the four seasons, we are invited to make adjustments to our daily habits in order to keep our health in balance through the change of seasons.
This posture can be a good part of a sun salutation sequence.
