Kúrma-nádyám sthairyam
Stability [comes from saṁyama] on the tortoise nadi
The thoracic cage and sternum or “heat centre” and diaphragm is the place of prana, a very important breathing space. The same is likened to a tortoise withdrawing into its shell, protecting its vital organs. It also serves to describe a particular meditative focus which brings about stability in mind and body.
