“And, in the Prāṇāyāma also, the different types,
like Vaikharī, the different Vṛtti, the different Krama,
he put them all into practice.
One of the greatest contributions,

is the use of Bāhya Kumbhaka,
and the importance of Recaka, or exhalation.”
– TKV Desikachar from lectures on ‘The Yoga of T Krishnamacharya’,
given at Zinal, Switzerland 1981.
