We are building a more complete practice, now with the two most important preparatory techniques together: Uddiyana Bandha Kriya and Agni Sara.
With Uddiyana Bandha Kriya we compress and massage the belly. With Agni Sara we give it space.
Sitali and Ujjayi take this further. They are two of the most foundational pranayama practices, preparing the body for the channelling of prana.
Do not practise Uddiyana Bandha Kriya, Agni Sara and Kapalabhati if you are pregnant or on your menstrual cycle.
