The practice
The verse describes opening the mouth, turning the tongue up towards the centre of the palate, fixing attention on the middle of the tongue, and feeling the sound HA being uttered there.
What it works on
A precursor of the khechari practices. The accessible core is the attention, not the tongue position: attending to the middle of the tongue and to the soft breath-sound HA is a real practice on its own, and is what dharana 21 offers.
Notes
- Dharana 21 gives the safe form of this — the HA sound and its dissolving, with the tongue left alone.
Practise gently
Shoonyaka offers educational and contemplative material, not medical, psychological or religious authority. Nothing here diagnoses or treats any condition. Stop any practice that leaves you dizzy, frightened or unwell, and treat a strong reaction as a reason to rest rather than to push on.
