"Yin yoga is an art form not an exact science. The purpose of Yin yoga is to take us out of the systems of social convention, indoctrination, and mechanistic ways of thinking, not to reinforce them by demanding conformity to rigid, limited paradigms. The practice of Yin yoga poses does not require scientific approval or validation. Intellectualizing the practice of Yin yoga serves to obstruct a deeper understanding of its essence. The real power to authorize truth is contained within each and every one of us."
