Sutra Neti demonstration by Master Paalu Ramasamy from Tirisula Yoga during a 200 Hr Yoga Teacher Training Course in Singapore. Sutra means thread and Neti means nasal cleansing. Neti is one of the six purification techniques known as Shat Kriya as documented in the literature, Hatha Yoga Pradipika. Neti helps to clean the nasal passage ways, removing excess mucus and stimulate the nerves to make the brain more alert.
Do not practice this on your own without guidance from a Yoga teacher.
