If you want to start practicing Yin Yoga, it is important that you familiarize yourself with the concepts of "Yin" and "Yang". Yin" is associated with slow, soft, passive and cold as well as the elements water, earth, moon, femininity and night. The "Yan" we relate to the fast, hard, active and hot and is also associated with fire, sun, masculinity and day. These are two opposing forces that are not only found in nature but also in our body and mind. Although the two concepts are opposites, they complement each other and should be in balance and harmony.
Therefore, in the practice of yoga we find more passive postures that activate our Yin energy, while other postures are more dynamic and activate the qualities of Yang. In Yin Yoga, specific asana sequences are used to stimulate our vital energy (prana) through the energy channels (nadis) to reach a level of balance and harmony.
