Pratyahara is the fifth of the eight limbs of yoga according to Patanjali's Yoga Sutras. It refers to withdrawing or turning the senses away from external objects. This allows the mind to achieve stability and prepare for deeper meditation. Techniques like pranayama, yoga nidra, trataka candle gazing and connecting/disconnecting with each sense in meditation can help achieve the state of pratyahara and sensory withdrawal. Pratyahara is important for controlling the mind and senses in order to progress along the yoga path towards samadhi.
