3.42

niśi cātyayike kārye daṇḍī maulī sahāyavān |

prāvṛtya paryaṭedrātrau na prāvṛtya śiro 'hani ||

jāṅgalaṃ bhakṣayedvājaṃ māsaṃ pittayutaṃ yakṛt ||

diśānayaivāśu yateta siddhyai jyotirhi śāstraṃ nayadurnayānām ||

tṛṭdāhamohān pūyasya chardanaṃ ca pravartayet |

rakaṃ ca sarvamārgebhyo 'riṣṭotpattiṃ ca taṃ tyajet ||

And at night on urgent business, [he should go] carrying a staff, wearing a headdress, and with a companion;

He should wander at night covering [his head], but not covering his head by day.

He should eat the liver of an arid-zone animal, or of a goat, accompanied by bile.

In this very direction he should quickly strive for success; for the treatise is the lamp regarding proper and improper conduct.

Thirst, burning sensation, and confusion; and he may start vomiting pus,
and [discharge] blood from all passages, with the emergence of fatal signs—one should abandon him.
