One should cook a pātra of ghee in a hundred times as much fresh juice of vidārī;
when prepared, one should cook it again in a hundred times as much cow's milk.
Combined with one-fourth parts each of sugar, tugākṣīrī,
honey, ikṣuraka, long pepper, and ajaḍā,
the physician should make pills the size of a large udumbara fruit;
from their use, a man becomes excited like a sparrow.
(Thus end the virilising pills.)
A hundred palas of rock sugar, half of that of fresh ghee,
combined with a one-fourth part of honey, one should cook with a fourth part of water.
Spreading a quarter part of thick wheat flour on a clean, smooth,
wide stone slab, one should knead it into a paste.
Pure pancakes resembling the disc of the moon should be made;
from their use, a man can satisfy women like an elephant.
(Thus ends the virilising pancake.)
Whatever is sweet, unctuous, life-giving, nourishing, heavy,
and gladdening to the mind, all that is called virilising.
Therefore, saturated with such substances, one should approach a woman,
aroused by one's own urge and delighted by the woman's qualities.
Having copulated, bathed, and drunk milk or meat soup, a man should lie down;
in that way, his semen and strength are replenished further.
Just as the fragrance of a flower bud is not perceived,
but is perceived once it blossoms, so indeed is semen in embodied beings.
Not before sixteen years and not beyond seventy
should a man desiring longevity engage in union with women.
For a boy who is too young, whose tissues are all incomplete, in approaching a woman,
would dry up suddenly, like a pond with little water.
Just as wood that is dry, un-unctuous, insect-eaten, and dilapidated
crumbles quickly when touched, so does an old man in approaching women.
Through old age, anxiety, diseases, over-exertion from physical labor,
fasting, and excessive indulgence in women, semen suffers depletion.
From depletion, fear, lack of confidence, grief, seeing faults in a woman,
being insensitive to the aesthetic pleasure of women, absence of desire, and lack of indulgence—
even when well-nourished, one does not have the capacity to approach women.
