yoṣav eṣāṃś ca nāgarakān prayeṇa antaḥpurikāḥ paricārikābhiḥ saha praveśayanti/

By means of their female attendants the ladies of the royal harem generally get men into their apartments in the disguise or dress of women. Their female attendants, and the daughters of their nurses, who are acquainted with their secrets, should exert themselves to get men to come to the harem in this way by telling them of the good fortune attending it, and by describing the facilities of entering and leaving the palace, the large size of the premises, the carelessness of the sentinels, and the irregularities of the attendants about the persons of the royal wives. But these women should never induce a man to enter the harem by telling him falsehoods, for that would probably lead to his destruction.
