The second book of the Yoga Sutra; Sadhana Pada, focuses on the Sadhaka or practitioner. No matter what anyone says, you can never be a "Yoga Master." Yoga is a constant practice, one in which we are always growing and moving forward.
Whatever you resolution for this year may be, I hope it is one which helps you to grow. Karma is that which keeps us from growing. It holds us back and keeps us stuck in a rut of non-thought. Our practice of Yoga helps us to find our dharma. Through effort, through practice, through constant study, we are able to discover our passion.
No matter how powerful your downward dog, how steady your handstand, Yoga will always offer you a new challenge. It is called a practice because of this. Because each breath that you take is new, each posture is different when you enter into it and each time you sit to silence your mind the citta is there needing to be quieted.
For this year, resolve to practice. To grow. To become more of your Self.
