Rachel Schaeffer's yoga programme is a method of uniting mind and body. There are postures, stories, and meditations to tone us spiritually as well as physically. Schaeffer shows how we can consciously develop twelve spiritual muscles, inner qualities such as acceptance, focus, flexibility, balance, peace, confidence, compassion, energy, and playfulness. The premise is simple: develop a flexible spine, and think more creatively; improve your physical balance and you can better balance work and play.
