हठयोग प्रदीपिका (योगी स्वात्माराम - ज्योत्स्ना टीका सहित सटीक)

50 HAṬHAYOGAPRADĪPIKĀ
68. By reason of that, the Kuṇḍalinī which is
asleep, feeling the extreme heat, is awakened, just as
a serpent struck by a stick hisses and straightens
itself.
69. Then it enters within the Suṣumnā, like
[a snake] which enters its hole. Therefore the Yogin-s
should every day and always practise Mūla-bandha.
70. Then the JĀLAṂDHARA-BANDHA [is described]:
Contract the throat and hold the chin firmly against
the chest [about four inches from the chest]. This is
the Bandha called Jālaṃdhara which destroys old age
and death.
71. Because it constricts the network (jāla) of
Nāḍī-s and [arrests] the downward course of the flow
of ambrosial water (jāla) [from the cavity in the palate],
this Bandha is Jālaṃdhara. It destroys all the maladies
of the throat.
72. When the Jālaṃdhara-bandha is practised,
by contraction of the throat, the nectar does not fall
into the [gastric] fire and the Prāṇa is not agitated
[i.e. not misdirected].
73. By the [firm] contraction of the throat the
two Nāḍī-s [Iḍā and Piṅgalā] are deadened. Here
[in the throat] is situated the middle Cakra (Viśuddhi).
This binds the sixteen ādhāra-s (vital centres).
They are the toes, ankles, knees, thighs, the perineum, the
generative organs, the navel, the heart, the neck, the throat, the
tongue, the nose, the centre of the eyebrows, the forehead, the head
and the Brahmarandhra, i.e. the upper opening of the Suṣumnā
Nāḍī in the skull.
