There is not so much technique this week. It is foundational work, preparing the ground and bringing us to calm and balance so that we can start to work with prana.
A free breath is essential for pranayama: no tension around the belly, which is what happens with stress. We work on this.
We use a double length exhale, because a long exhale engages the parasympathetic nervous system, the calming part of the nervous system.
