In exploring the principles that underpin the practice of Āsana the first idea to consider is that our practice is not just another form of exercise. Yoga Āsana are more than just physical postures or exercises to stretch and tone the body, or enhance our sense of personalised well-being. From within its Haṭha roots the concern of Yoga is our relationship with the force which is behind our movements and its source that initiates our every action.
Further the different practice elements that constitute a mature Yoga practice are not separate compartments. They are linked through the principles underpinning them. For example a respiratory competence learnt through the practice of Āsana facilitates progress within the seated practice of Prāṇāyāma. An enduring stable posture learnt through the practice of Prāṇāyāma supports the cultivation the meditative attitude inherent in progress towards Dhyāna or meditation.
