# Vayu
As long as the vayu (air and prana) remains in the body, that is called life.
Death is when it leaves the body. Therefore, retain vayu.Death is not total. The physical body dies or the mind dies, but not thesoul. Death is not extinction; it is a process of disintegration. Thecomponents of the body, the five tattwas: akasha ‘ether,’ vayu ‘air,’ agni,fire,’ apas ‘water,’ prithvi ‘earth;’which are associated with the five pranavayus, disintegrate and go back to their original source. Akasha tattwa goesback to akasha, vayu to vayu, agni to agni, apas to apas, prithvi to prithvi,and then the jivatma moves out.
This jivatma, spirit, ego, astral body, or whatever you might like to call it,is something which survives death. The pranas also do not die, they moveout of the body and return to their source. If death is to be averted theprocess unlinking all the three components i.e. prana, mind and soul, has tobe stopped.
Vayu means ‘air,’ but it doesnot refer only to the gross air and its chemical properties; it indicates pranicair. In the pranic body, pingala channelizes prana shakti, but prana vayumoves throughout the whole body like waves of energy. It can be likened toan electromagnetic field where the energy is in constant motion.
There are five main vayu functions, known as apana, prana, samana,udana and vyana. They are the different processes and manifestations of theone vayu, just as the various limbs of a man comprise the one body.
Pranic absorption takes place on a major scale in the thoracic region and isthe function of prana vayu. Elimination takes place largely through theurinary/excretory and reproductive organs and is powered by apana. Inbetween apana and prana, in the stomach region, is the area of assimilation,which is the function of samana. Movement in the throat and facialexpressions are due to udana. Circulation is powered by vyana whichpervades the whole body.
All the processes which affect absorption or inward movement ofthe subtle cosmic force are due to prana. Those which affectelimination or outward movement are due to apana. Assimilation,preservation and continuation are the work of samana. Ascension andrefining are the work of udana, and pervasiveness is the property ofvyana. These actions occur within the various realms of existence.The vayu, however, is specifically concerned with the pranic body orpranamaya kosha.
In the Upanishads, prana vayu is also called the ‘in breath,’ apanathe ‘out breath,’ samana the ‘middle breath,’ and udana the ‘upbreath.’ Prana vayu is inhalation, apana exhalation, samana the timebetween inhalation and exhalation, and udana, the extension ofsamana. According to the Maitri Upanishad , “Samana is thehigher form of vyana and between them is the production of udana.That which brings up or carries down what has been drunk or eaten isudana.”
