"Close the right nostril with the right thumb. Draw in the air very, very slowly through the left nostril. Then close the left nostril also with little and ring fingers of the right hand. Retain the air as long as you can comfortably do. Then exhale very, very slowly through the right nostril after removing the thumb. Now half the process is over. Then draw air through the right nostril. Retain the air as before and exhale it very, very slowly through the left nostril. All these six processes constitute one Pranayama."
"This Pranayama removes all diseases, purifies the Nadis, steadies the mind in concentration, improves digestion, increases the digestive fire and appetite, helps to maintain Brahmacharya and awakens the Kundalini that is sleeping at the Muladhara Chakra. Purification of Nadis will set in rapidly. You will have levitation (rising above the ground) also."
