On a practical level, the vinyasa concept of continuous flow aids the practitioner through movement (asana) that purifies the physical body, while mastery and refinement of the breath (pranayama) through concentration (dharana) quiets the senses (pratyahara), preparing the practitioner for meditation (dhyana) and eventually, Samadhi - the union of the soul with the divine. A balanced asana practice rests on ethical behavior (yama) and self-discipline (niyama). Under the guidance, the practitioner will begin to cultivate the eight limbs in practice.
