is Sanskrut word, meaning sound or note. It is also a continuous
flow of air through one nostril. Yog means union, so Swaryog is
a science which is realization of cosmic consciousness through control
and manipulation of breath.
Swar Yog is science which is a complete study, observations, control
and manipulation of breath or Swar. Pranayam is only related to
control of breath in various ways. In Swar Yog, you will find association
of breath in relation to activities of sun, moon, various seasons,
physical and mental conditions of individuals etc. So Swaryog is
more comprehensive in theory and practices related to breath.
