In the Yoga Sutras, this component is described by sage Patanjali as "sthirasukhamasanam". This means that the asana is a posture in which the body is completely at ease. The yogic discipline maintains that true ease of posture is attained only when the mind is focused. On practicing asanas, the mind is to be focused on holding the various postures, and hence the body attains a state of comfort.
