“He has very clear ideas on the Ṣat Kriyā and the Mudrā.
He believes that if a person does Āsana properly, with breathing,
and has certain restraints regarding food, there is no need for these Kriyā.”
– TKV Desikachar from lectures on ‘The Yoga of T Krishnamacharya’,
given at Zinal, Switzerland 1981.
