By Swami Harshananda
Sometimes transliterated as: Nagavayu, NAgavAyu, Naagavaayu
Nāgavāyu literally means ‘the air or prāṇa that does not move’.
Life and health of the human body are maintained by the pañcaprāṇas or the five vital airs. Nāgavāyu, also called nāga, is an upaprāṇa, a minor prāṇa, considered as an aspect of udāna. It is responsible for bringing about eructation and vomiting.
