The language of Yog is Sanskrit.
A Yoga class or self Practice often starts with chanting of Om .
Om is sound, and sound vibrates through space.
The inner and outer space.
Om takes its origins from the fusion of A U M ,
each sound evokes one dimension accessible to the Human Being.
A : Reality as perceived through senses
U : Dream State
M : Deep Sleep
Silence : the state that encompasses them all
