Within a yin class, postures are typically released into- as opposed to held onto- anywhere from three to five minutes in length or longer. The student lets go of as much muscular effort as possible in order to release fascia and maintain the health of connective tissue. The result is greater range of motion and increased joint stability. On a mental, emotional and energetic level, yin yoga has the capacity to change your life by changing your lens on life; increasing the flow of prana (qi) in the body. The opportunity for insight, wellness and growth is truly exponential. It also helps to encourage, nourish or deepen a mindful meditation practice. But, it's one thing to be aware and something completely different when put into practice. You cannot understand the capacity that (yin) yoga has to better your world, life and perspective until you combine action with theory.
Surrender the body.
Surrender the mind.
Give over to the spirit-
and get back in control.
