This is my teacher Mark Whitwell.
He is one of the few people still alive that have learned directly with Krishnamacharya and his son Deskichar.

Krishnamacharya is responsible for bringing down Yoga from the Himalayas. Making Yoga available to “householders”.

We are householders. We participate in all aspects of life.
Our participation in all ordinary conditions is the embrace of life itself.
Heart beating, breath breathing. We are creation itself.
This is Tantra.
