THE MANIFESTATIONS OF PRANA 



WHAT we know as the manifestations of 

 Prana are the periodic changes of its 

 center of activity from one vital func-

 changes in the flow of the Tattvas. 



For these manifestations of Prana are of course 

 manifestations of various Tattvic activities. Con- 

 cerning this the Upanishad explains : " As the 

 paramount power appoints its servants, telling 

 them, ' Rule such and such villages,' so does the 

 Prana. It puts its different manifestations (its 

 elemental servants) in different places," and they 

 follow in the order in which the flow of the Tatt- 

 vas succeed one another; by the "flow" being

 can be renewed. Whether waking or sleeping,
