हठयोग प्रदीपिका (योगी स्वात्माराम - ज्योत्स्ना टीका सहित सटीक)

HAṬHAYOGAPRADĪPIKĀ 19
purification of the Nāḍī-s, Mudrā-s, etc. and control
of breath.
56. Āsana-s, the varieties of Kumbhaka, the
positions called Mudrā [i.e. Mahāmudrā, etc.], then
concentration upon the nāda (inner sound) comprise the
sequence of practice in Haṭha-yoga.
57. The Brahmacārin [one devoted to Brahman,
who leads a chaste life] who, following a moderate
diet, is intent on Yoga, renouncing [the fruits of his
actions], becomes a Siddha after a year. There need
be no doubt about this.
58. 'Moderate diet' is defined to mean agreeable
and sweet food, leaving one-fourth of the stomach
free, eaten [as an offering] to please Śiva.
The Yogin should fill two parts of his stomach with food
and the third with water, leaving the fourth free for the passage
of air. 'Pleasing Śiva' means that he should think that the one
who eats is Śiva and not himself; as the Śruti-s say: 'The eater is
Maheśvara, the great Lord.'
59. The following things are said to be unsalutary
[for Yogin-s]: Things that are bitter, sour, pungent,
salty, heating, green vegetables [other than those or-
dained], sour gruel, [sesame or mustard] oil, sesamum,
mustard, alcohol, fish, flesh including that of the goat,
curds, buttermilk, horse-gram, the fruit of the jujube,
oil cakes, asafoetida and garlic.
By 'bitter', substances such as bitter gourd are meant. Sour
such as tamarind; pungent such as chillies; heating such as jaggery,
which increase the temperature of the body.
