“Cakra Bhāvana on the Breath within Twisting Āsana…
To present guideline focus points, when exploring the
relationship of Directional Breathing and Directional
Movement within the body in Parivṛtti Āsana.
Illustrated here within Jaṭhara Parivṛtti, as a sensing
of the breath linked to a progressive spiral movement
within the trunk, and felt within the length of the spine.
It is a descending and an ascending Cakra Bhāvana
supporting the length and subtlety of the breath within
the body on both the inhalation and the exhalation.
Here, the Pūraka, or inhalation is felt as if, from the
Viśuddhi Cakra downwards through both the Anahāta
Cakra and the Maṇipūra Cakra,  to the Svādhiṣṭhāna Cakra.
Whereas the Recaka, or exhalation is felt as if, from the
Svādhiṣṭhāna Cakra upwards through both the Maṇipūra
Cakra and the Anahāta Cakra, to the Viśuddhi Cakra.”
