Chin Mudra
This mudra alters the breath by encouraging abdominal breathing.
Chinmaya Mudra
This mudra encourages intercostal breathing through the expansion of the sides of the ribcage and the middle of the torso.
Adhi Mudra
This mudra breathing encourages clavicular breathing through the expansion of the upper body of the lungs.
Brahma Mudra
This mudra encourages deep and full breathing. While you use it, observe each complete inhalation, which begins at the abdominal, moves up to fill the middle and side ribs and finally competely fills the very tips of the lungs right up under the collarbone. As you exhale, become aware of the gentle contracting force as the air flows out of the lungs through the nostrils.
