The word Yoga comes from the Sanskrit word 'yuj' meaning to yoke,
join or unite.
It is a philosophical science of self - realization and transformation,
independently guiding one into recognizing his fullest potential
and purpose in life (Essence of spirit).
The origin of yoga pre-dates Indian Hindu and Buddhist religions
and in that context, Yoga is not a religion.
In Yogic philosophy we have three bodies; the Physical, Subtle
(astral) and Causal (spirit), which is the path to the integration
of self or "self realization".
