śaktiviṣaye ca pratidinaṃ niṣkrāmet//

As for the man himself he had better not enter a royal harem, even though it may be easily accessible, on account of the numerous disasters to which he may be exposed there. If however he wants to enter it, he should first ascertain whether there is an easy way to get out, whether it is closely surrounded by the pleasure garden, whether it has separate enclosures belonging to it, whether the sentinels are careless, whether the King has gone abroad, and then, when he is called by the women of the harem, he should carefully observe the localities, and enter by the way pointed out by them. If he is able to manage it, he should hang about the harem every day, and, under some pretext or other, make friends with the sentinels, and show himself attached to the female attendants of the harem, who may have become acquainted with his design, and to whom he should express his regret at not being able to obtain the object of his desire. Lastly he should cause the whole business of a go-between to be done by the woman who may have access to the harem, and he should be careful to be able to recognize the emissaries of the King.
