Yin Yoga contains the ancient, and some say original, form of asana practice.
The sages who pioneered the path of yoga used asanas to strengthen the body, so that they could sit for long periods in contemplative meditation. If you have ever sat for a long time with legs crossed, you know the hips and lower back need to be strong and open. The sensations you felt were deep in the connective tissues and the joints. These are the deep yin tissues of the body, relative to the more superficial yang tissues of muscles and skin.
Yin Yoga opens up these deep, dense, rarely touched areas. This is wonderful for people who are less flexible as you spend the majority of the time on the floor – it is wonderful for people suffering from back pain and anxiety and depression. In Winter the class is in candlelight.
