Never fear, you won’t get bored! While the sequence of postures and breathing exercises are always the same, you will find your practice is different every day. We keep it consistent for these reasons: mastery, concentration, meditation, and self-realization.
Mastery: As a beginner, not having to anticipate what will come next helps create a shorter learning curve. The repetition helps you to see progress in posture accuracy and depth, and to measure how much your mind & body improve with a consistent practice. Mastery of anything creates the possibility of skillful living.
Concentration: Concentration is more available when there is not constant change and surprise. No distractions!
Meditation: The practice may appear to be just physical activity, yet it is also a form of moving meditation. Especially in coordination with our dialogue (the words we use to teach), the repetition of the series deepens your ability to concentrate on the present action and frees us from the overthinking, overanxious part of our brains.
Self-Realization: Over time you start to see your habitual reactions and, as a result, to dissolve them. You learn that your experience is created by you, not by what is external. You observe your development under the microscope of the repeated postures and sequence. By building this awareness of your thoughts and emotions and how they change over time, you develop insight.
All of this is eventually taken from the yoga mat into life, as you become able to target your deeper levels of self and harness your full power.
