52 HAṬHAYOGAPRADĪPIKĀ
81. If he stints his diet, the fire quickly consumes
[the body]. On the first day he should stand for a
moment upon his head, with his feet above.
The process is this. The body should be raised in the air
by resting the back of the head and neck and shoulders upon the
ground, supporting the hips with the hands, the elbows resting on
the ground if required.
82. Practise this by increasing the duration gra-
dually every day. After six months wrinkles and grey
hair disappear. He who practises this for a yāma
(i.e. three hours) daily, conquers death.
83. Then VAJROLĪ [is described]: Even someone
living an unrestricted life, without the disciplines
prescribed by Yoga, if he knows well [by practice] the
Vajrolī, becomes the repository of the siddhi-s.
84. Here I mention two things that are difficult
for anyone to obtain: the one is milk [at the proper
time] and the other, a woman who acts according to
one’s wishes.
Attention is drawn to the previous note (III. 43) pointing
out that such statements should not be taken literally.
85. At the time of [the emission of the seminal
fluid during] sexual intercourse, practise slowly and
well to draw [it] up. Thus a man or a woman will
obtain success in Vajrolī.
86. Blow with effort into the hole of the penis
through a prescribed tube very slowly so as to allow
the passage of air.
