From saṃyama on the throat cavity, hunger and thirst cease.

Kaṇṭha is throat. Kūpa is cavity, well. Kṣut is hunger. Pipāsā is thirst. Nivṛtti is cessation.

The throat cavity (kaṇṭha kūpa) is the area below the tongue, where viśuddhi chakra resides.

Through saṃyama on this point, the yogī can control the sensations of hunger and thirst, allowing prolonged fasts without discomfort.

This siddhi is practical for intensive retreats or situations where food is scarce. It is not for showing off but for freeing the body from its demands.

Physiologically, this area is connected with appetite regulation. Saṃyama directly affects the control centers.

Haṭha yoga texts describe a technique called khecarī mudrā, where the tongue is placed in this cavity. The effect is similar.

It is not that the body ceases to need nutrition, but that the urgency signals are suspended, giving freedom to the yogī.
