Asana originally meant a sitting position. In the practice of Yoga it denoted the art of sitting still but later was applied to any posture useful for restoring and maintaining a practitioner’s well-being and improving the body’s flexibility and vitality, cultivating the ability to remain in seated meditation for extended periods. Such asanas are known in English as “yoga postures” or “yoga positions”. Any way that we may sit or stand is an asana while a posture used in yoga is called a yogasana.
All Asanas denote physical (sargun) and spiritual (nirgun) characteristics & benefits. Valuing the cause of both helps keep a balance in our daily practice and our everyday life.
