“Each practice session is a journey. Endeavor to move with awareness and enjoy the experience. Allow it to unfold as a flower opens. There is no benefit in hurrying. Yoga grows with time. Some days are easy and the mind is calm and the physical body is light and responsive. Other days you may find that the mind is running wild and the body feels like wet cement. We must breathe deeply and remain detached. Asanas are not the goal. They are the vehicle to access a deeper internal awareness. Create a practice that best suits your personal needs so that it is something that you look forward to. Yoga is a place of refuge and a soothing balm for the stresses of modern life. Within each practice find ways to refine your existing understanding so that you continue to grow.”
