Yoga is an ancient Indian body of knowledge that dates back more than 500 years. The word "Yoga" came from the Sanskrit word "yuj" which means "to unite or integrate." Yoga then is about the union of a person's own consciousness and the universal consciousness.
Ancient Yogis had a belief that in order for man to be in harmony with himself and his environment, he has to integrate the body, the mind, and the spirit. For these three to be integrated, emotion, action, and intelligence must be in balance. The Yogis formulated a way to achieve and maintain this balance and it is done through meditation,exercise and breath.
Breathing techniques were developed based on the concept that breath is the source of life. In Yoga, students gain breathing control as they slowly increase their breathing. By focusing on their breathing, they prepare their minds for the next step.
