"Prāṇa, Apāna, Samāna, Uḍāna, Vyāna, Naga, Karma, Kṛkara, Devaḍaṭṭa, and Ḍhanañjaya—these ten vāyus (vital airs) move in all the nādis. Prāṇa moves in the nostrils, the throat, the navel, the two great toes and the lower and the upper parts of kunḍalinī. Vyāna moves in the ear, the eye, the loins, the ankles, the nose, the throat and the buttocks. Apāna moves in the anus, the genitals, the thighs, the knees. the stomach, the seeds, the loins, the calves, the navel, and the seat of the anus of fire. Uḍāna lives in all the joints and also in the hands and legs. Samāna lives, permeating in all parts of the body. Along with the fire in the body, it causes the food and drink taken in, to spread in the body. It moves in the seventy-two thousand nādis and pervades all over the body along with the fire. The five vāyus beginning with Naga go towards the skin, the bones, etc. The Prāṇa which is in the navel separates the food and drink which is there and brings about the rasas (juices) and others. Placing the water above the fire and the food above (or in) the water, it goes to the Apāna and along with it, fans up the fire in the centre of the body. The fire thus fanned up by the Apāna gradually increases in brightness in the middle of the body. Then it causes through its flames the water which is brought in the bowels by the Prāṇa to grow hot. The fire with the water causes the food and condiments, which are placed above, to be boiled to a proper degree. Then Prāṇa separates these into sweat, urine, water, blood, semen, the fæces and the like. And along with the Samaria, it takes the juice (or essence) to all the nādis and moves in the body in the shape of breath. The vāyus excrete the urine, the fæces, etc., through the nine openings in the body which are connected with the outside air. The functions of Prāṇa are inspiration, expiration, and cough. Those of Apāna are the excretion of the fæces and the urine. Those of Vyāna are (such actions as) giving and taking. Those of Uḍāna are keeping the body straight, etc. Those of Samāna are nourishing the body. Those of Nāga are vomiting, etc.; of Kūrma, the movement of the eyelids; of Kṛkara, the causing of hunger, etc., of Ḍevaḍaṭṭa, idleness, etc., and Ḍhanañjaya, phlegm.
