Prāṇāyāma Pointer 15 – Relationship between the nostrils and the chest in Nāḍī Śodhana
When using Mṛgi Mudrā in Nāḍī Śodhana
the control should not be at the nose.
The fingers are a guide more than a valve.
Thus you should not bend the nose.
The main control for the Inhale and for
the Exhale is in the chest not the fingers.
