It is that from which proceeds the wellordained universe, and it that upon which it depends. The vital airs called Prana, Apana, Samana, Vyana and Udana, flow from it, and it is that into which they again enter. The vital airs Prana and Apana move between Samana and Vyana.
यतः प्रवर्तते तन्त्रं यत्र च प्रतितिष्ठति। प्राणोऽपान: समानश्च व्यानश्चोदार एव च॥ तत एव प्रवर्तन्ते तदेव प्रविशन्ति च। समानव्यानयोर्मध्ये प्राणापानौ विचेरतुः॥
