"Nauli" means "to churn". It is a shatkarma technique that is a dynamic version of uddiyana bandha (abdominal lock) and consists of twirling the abdominal muscles, first in one direction, and then the other. Nauli stimulates the higher functioning of the digestive system by raising ecstatic kundalini energy up from the pelvic region into active participation with food and air in the GI tract, leading to whole body ecstatic conductivity. In the process, it provides stimulation for deep cleansing in the bowels.
