O great hermit! I am going to describe about Pratyahara. Pratyahara is a process by which all sensory organs usually enjoying and attracted towards the worldly pleasures are to call back forcibly. Whatever is observed by a man, that all is Brahma and this presumption or understanding when attained, the concentration of mind thereupon is called 'Pratyahara' as it is defined by the person, known to Brahma.
A surrender of all activities either good or bad performed by a man throughout his life to the god or the supreme soul is also called Pratyahara.
In other words, Pratyähära is a concept that enables a man to perform all desired activities, presuming that these are in the form of service to the god.
To worship the lord by performing all desired activities too is called Pratyahára.
To worship the lord by performing all desired activities too is called Pratyahára. So far as Pratyahara as an exercise is concerned, the man should establish the wind from one place to another
like from the route of teeth to the throat, from throat to the heart, from heart to the navel region,
from navel region to the Kundalini, from Kundalini to Maladhara,
from Maladhara to the region of waist and from there to the middle of the pubic region. Then it should be transferred to the knees, from the knees to the thighs and from thighs to the thumb of feet.
The scholars expert in Pratyāhāra since ancient period has named the above said exercise as 'Pratyahara'.
All evils as also all ailments in the form of birth and death are automatically eliminated if the Pratyahara is made by aforesaid manner.
The scholar should sit in Svastika posture, keep his mind free from tensions, inhale the breathing air through both nostrils and carry it over all regions starting from the foot to the head. He should retain the breathing air on both feet, Muladhara, navel region, middle region of heart, at the root of throat, palate, in the middle of brows, forehead and in the head. The retention of the breathing air gradually on these all parts of the body is called 'Pratyähära'.
The learned person should do concentration in mind, separate the feeling of soul from the body and making himself free from fatigues, do concentration on his inner soul exclusively.
The scholars of the Vedanta element has told this the real Pratyahara. Nothing is scarce to gain for the man who does exercises on Pratyahara by the aforesaid manner.
