From a metaphysical point of view breath is the life current, prana. This life current exists also in things, such as the gut or the string or the skin of the drums. There is also a part of life in these things, and it is to that extent that their life current becomes audible, and that it touches the life current of the living creatures and gives it an added life. It is for this reason that the most primitive tribes who have only a drum to play, or an instrument to blow, get into such a condition by that continual playing of the drum that they enjoy the state of ecstasy.
