Flexibility goes a long way in yoga, but flexibility of the mind is far more important to create growth. Yoga is an ancient Indian physical, mental and spiritual practice designed to allow its practitioner to reach a permanent state of peace. Through breath work, meditation, the physical practice of asanas/poses, and introspection, the practitioner is said to attain another state of consciousness. Yoga is a Sanskrit word that roughly translates to "union" -- often translated as a union of mind, body and spirit.
Yoga is an ongoing practice that teaches us to look within. For some, it can be life-changing; for others, it is simply physical exercise. Whatever its purpose, "Yoga is a powerful vehicle for change. As you build strength, you start to believe in your own potential." - Tiffany Cruikshank
