"When a man is excessively attached to a woman, he is afraid of her coming into contact with other men; he does not then regard or notice her faults; and he gives her much wealth through fear of her leaving him."
"A courtesan should be agreeable to the man who is attached to her, and despise the man who does not care for her. If while she is living with one man a messenger comes to her from some other man, she may either refuse to listen to any negotiations on his part, or appoint a fixed time for him to visit her, but she should not leave the man who may be living with her and who may be attached to her."
"A wise woman should only renew her connection with a former lover if she is satisfied that good fortune, gain, love, and friendship, are likely to be the result of such a re-union."
When a courtesan is able to realize much money every day, by reason of many customers, she should not confine herself to a single lover; under such circumstances, she should fix her rate for one night, after considering the place, the season, and the condition of the people, and having regard to her own good qualities and good looks, and after comparing her rates with those of other courtesans. She can inform her lovers, and friends, and acquaintances about these charges. If, however, she can obtain a great gain from a single lover, she may resort to him alone, and live with him like a wife.
Now, the Sages are of opinion that when a courtesan has the chance of an equal gain from two lovers at the same time, a preference should be given to the one who would give her the kind of thing which she wants. But Vatsyayana says that the preference should be given to the one who gives her gold, because it cannot be taken back like some other things, it can be easily received, and is also the means of procuring anything that may be wished for. Of such things as gold, silver, copper, bell metal, iron, pots, furniture, beds, upper garments, under vestments, fragrant substances, vessels made of gourds, ghee, oil, corn, cattle, and other things of a like nature, the first, viz., gold, is superior to all the others.
When the same labour is required to gain any two lovers, or when the same kind of thing is to be got from each of them, the choice should be made by the advice of a friend, or it may be made from their personal qualities, or from the signs of good or bad fortune that may be connected with them.
