By Swami Harshananda
Nauli is one of the ṣaṭkarmas or six purificatory acts. It consists of moving the muscles of the belly forcibly from the left to the right in a wavy fashion. It removes dispepsia and increases the power of digestion. However, it is to be learnt and practiced under expert guidance.
