The meaning of Yoga is to unify - that is, to unify all of what we consist of into wholeness. In the practice of Vinyasa Yoga, we achieve this unity through the unfolding of a clearly outlined sequence of poses, linked by the breath.
The cycle of the vinyasa brings us into a more balanced state, through the use of our fluid body movements, the breath, sound and silence. There are no special requirements to join this flow - just be open and willing.
This flow feels, to me, like a creative unfolding of ones Self through the practice. 
The fluidity of the vinyasa mirrors our daily lives – dealing with constant change, enriching and challenging surprises and humble beginnings.

The Yin Yoga practice uses soft, deep long-holding postures, that stretch connective tissue and joint sites, while muscles are relaxed. Connective tissue does not stretch like muscle, and will not respond well to brief stresses, hence the poses being held for longer periods of time. These long held poses, together with the breath as the anchor, enhance the meridian and organ systems of the body, helping to enrich and enliven the body, heart and mind. This practice is also a preparation for deepening ones mindfulness meditation practice, and thus becoming aware of our natural state of „beingness“.
