About asana practice:
Translated, Yoga means ‘unity’. By physically practicing hatha yoga, you unify mind and body, and become aware of the interaction between the two. You practice sensing who you are energetically, what the effect of that state is on the body and vice versa. In doing so, you expand consciousness. Yoga poses (asana) have physical, psychological and energetic effects. Ultimately, it is a preparation for meditation.
Practicing hatha yoga, we hold poses a little longer. This builds strength, flexibility and concentration. It helps us to go inward and experience a Sense of Self. By learning more about the philosophy, we deepen our understanding about yoga as a self-realization practice.
