Udgeeth involves chanting of AUM (OM) with every exhalation.
We do Udgeeth in a sequence of Pranayam like Bhastrika, Kapalbhati, Anulom Vilom, Bhramari and then Udgeeth.
Is Udgeeth one of Pranayam(One of 8 limb of Ashtanga yoga)?
In which book Udgeeth is mentioned? I guess its not mentioned in Yoga Sutras of Patanjali and Hatha Yoga Pradipika.
