Today's theme is Vyana Vayu - the movement of energy to the periphery from the centre. I think of it physically as like the circulatory and pulmonary system. If you think of the breath as your life force energy (Prana) which enters the body via Prana Vayu. Then Vyana Vayu is the flow which carries that energy from the centre to the extremities.
As always we'll check-in with ourselves, take a moment to breathe (with an interrupted inhale breath)
