“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.”
