“The practices dealing with the body and the
breath are known as Āsana and Prāṇāyāma.
They are interlinked, in Āsana the body is
the focus and the breath serves this focus.
In Prāṇāyāma the regulation of the breath is the focus,
the body is prepared adequately via Āsana for this
regulation to materialise without any resistance.”
– TKV Desikachar Madras 1996

“The ‘seed’ of potential for Ujjāyī as an
Ajapā Mantra abides within the ‘shell’ of
a Bhāvana for Ujjāyī as a Dhāraṇā Deśa.
The Deśa also needs to be supported by
utilising a locationally relevant Ādhāra,
as in this instance, the Viśuddhi Ādhāra.
Further considerations can be around the
linking of the sound of Ujjāyī to a semantic
thought-form, by adding Mano Japā Rūpa to
this Ajapā, as some do through using Haṃsa.
However, one could argue that this formation,
shifting from a non-language feeling-based
experience into a language thought-based
experience, can detract from the Bhāvana,
in that a unique Lakṣaṇa of Ujjāyī resides in
the notion of ‘sounding’ without language.”
