Yama and niyama control the yogi’s emotions and serve to maintain harmony. Asana practice keeps the body healthy and strong and in harmony with nature. Pranayama teaches the regulation of breath and thereby control of the mind. These first four stages form the outward quest.Pratyahara is considered a transitional state which takes the yogi inward. When the body has been tempered by asana, when the mind has been refined by the fire of pranayama and when the senses have been brought under control by pratyahara, the yogi reaches the sixth stage dharana. The mind is stilled in order to achieve this state of complete absorption. When the flow of concentration, dharana, is uninterrupted the state that arises is dhyana, meditation.
Samadhi is the end of the yogi’s quest. At the peak of meditation the state of samadhi is entered where body and senses are at rest but the faculties of the mind and intelligence are alert as if awake. A person in the samadhi state is fully conscious and alert.
