The Jâlandhara Bandha.
Contract the throat and press the chin firmly against the chest. This is called Jâlandhara Bandha, which destroys old age and death. 69.
It stops the opening (hole) of the group of the Nâdîs, through which the juice from the sky (from the Soma or Chandra in the brain) falls down. It is, therefore, called the Jâlandhara Bandha —the destroyer of a host of diseases of the throat. 70.
In Jâlandhara Bandha, the indications of a perfect contraction of throat are, that the nectar does not fall into the fire (the Sûrya situated in the navel), and the air is not disturbed. 71.
The two Nâdîs should be stopped firmly by contracting the throat. This is called the middle circuit or centre (Madhya Chakra), and it stops the 16 âdhâras (i.e., vital parts). 72.
Note.—
The sixteen vital parts mentioned by renowned Yogîs are the (1) thumbs, (2) ankles, (3) knees, (4) thighs, (5) the prepuce, (6) organs of generation, (17) the navel, (8) the heart, (9) the neck, (10) the throat, (11) the palate, (12) the nose, (13) the middle of the eyebrows, (14) the forehead, (15) the head and (16) the Brahma randhra.
By drawing up the mûlasthâna (anus,) Uḍḍiyâna Bandha should be performed. The flow of the air should be directed to the Suṣumnâ, by closing the Idâ, and the Pingalâ. 73.
The Prâna becomes calm and latent by this means, and thus there is no death, old age, disease, etc. 74.
These three Bandhas are the best of all and have been practised by the masters. Of all the means of success in the Haṭha Yoga, they are known to the Yogîs as the chief ones. 75.
The whole of the nectar, possessing divine qualities, which exudes from the Soma (Chandra) is devoured by the Sûrya; and, owing to this, the body becomes old. 76.
To remedy this, the opening of the Sûrya is avoided by excellent means. It is to be learnt best by instructions from a guru; but not by even a million discussions. 77.
