Pratyahara is a combination of two Sanskrit words prati- (against) and ahara (food,diet or intake”)
Pratyahara means not taking any input or any information from the sense organs. It is a process of retracting the sensory experience from external objects. It is a step of self extraction and abstraction. Pratyahara is not consciously closing one’s eyes to the sensory world, it is consciously closing one’s mind processes to the sensory world. Pratyahara empowers one to stop being controlled by the external world, fetch one’s attention to seek self-knowledge and experience the freedom innate in one’s inner world.
Pratyahara marks the transition of yoga experience from first four limbs that perfect external forms to last three limbs that perfect inner state, from outside to inside, from outer sphere of body to inner sphere of spirit.
