Quote reads: Yoga, an ancient but prefect science, deals with the evolution of humanity. This evolution includes all aspects of one's being, from bodily health to self realization.
Yoga means union - the union of body with consciousness and counciousness with the soul. Yoga cultivates the ways of maintainting a balanced attitude in day to day life and
endows skill in the performance of one's actions. - B.K.S. Iyengar
