Nithya Kriya: Yogic Solutions for Eye, Ear, Nose and Throat Disorders
TRANSLATION
Having turned the tounge upwards, inhaling the air by producing the sound "seeth(hiss)" (because of inhalation), hold the breath and then exhale through both the nostrils. Concentrate on the tounge and the sound created by the air. This is called Seethkaaree Kumbhaka – the bestower of great Siddhis to the sadhus.
