"Yin Yoga: Outline of a Quiet Practice" brings together in a fresh way the ancient wisdom of acupuncture and Taoism with Hindu yoga practices. The Yin aspect of Yoga (using postures that stretch connective tissue) is virtually unknown but vital for a balanced approach to physical and mental health. Paul Grilley outlines how to practice postures in a Yin way. Grilley includes an explanation of Modern Meridian Theory, which states that the meridians of acupuncture theory are currents flowing through the connective tissues of the body. "Yin Yoga" is specifically designed to address these tissues. For yoga practitioners looking for something beyond physical postures, "Yin Yoga" addresses the deeper spiritual dimensions of yoga, with helpful sections on chakras, breathing exercises, and meditation.
