In traditional yoga, pratyahara
(withdrawal of the senses) is one of the Eight Limbs of Yoga as
described in Patanjali's Yoga Sutras and a key component on the path
The indriyas include the manas (sensory
or processing mind), the five karmendriyas (means of expression, action or senses) and the five jnanendriyas (wisdom or knowing senses). As part of yogic meditation, the yogi perceives the world through the
jnanendriyas and responds via the karmendriyas. The manas is affected
by what it perceives through the indriyas.
Jnanendriyas are the five lower sense
organs, referred to as ears (shotra), eyes (chakshu), nose (grahnu), tongue (jivha) and skin (tvak).
Karmendriyas are the organs that interact with the material world. The feet (pada) move, the hands (pani) grasp and hold, the rectum (payu) eliminates, the genitals (upastha) procreate and the mouth (vak) speaks.
