Prāṇāyāma Pointer 7 – Antar Kumbhaka and lengthening the breath……
When using the Antar Kumbhaka to lengthen the breath,
always factor in its effect on the length of the exhale.
It should be able to stay the same length and quality.
If it is affected, change the length of the Kumbhaka,
rather than compromising the flow of the breath.
