When one of the two lovers is grateful, and the other liberal, some Sages say that the liberal one should be preferred, but Vatsyayana is of opinion that the former should be chosen, because liberal men are generally haughty, plain spoken, and wanting in consideration towards others. Even though these liberal men have been on friendly terms for a long time, yet if they see any fault in the courtesan, or are told lies about her by some other women, they do not care for past services, but leave abruptly. On the other hand the grateful man does not at once break off from her, on account of a regard for the pains she may have taken to please him. In this case also the choice is to be guided with respect to what may happen in future. When an occasion for complying with the request of a friend, and a chance of getting money come together, the Sages say that the chance of getting money should be preferred. But Vatsyayana thinks that the money can be obtained to-morrow as well as to-day, but if the request of a friend be not at once complied with, he may become disaffected. Even here, in making the choice, regard must be paid to future good fortune. On such an occasion, however, the courtesan might pacify her friend by pretending to have some work to do, and telling him that his request will be complied with next day, and in this way secure the chance of getting the money that has been offered her. When the chance of getting money, and the chance of avoiding some disaster come at the same time, the Sages are of opinion that the chance of getting money should be preferred, but Vatsyayana says that money has only a limited importance, while a disaster that is once averted may never occur again. Here, however, the choice should be guided by the greatness or smallness of the disaster. The gains of the wealthiest and best kind of courtesans are to be spent as follows: Building temples, tanks, and gardens; giving a thousand cows to different Brahmans; carrying on the worship of the Gods, and celebrating festivals in their honour; and, lastly, performing such vows as may be within their means. The gains of other courtesans are to be spent as follows: Having a white dress to wear every day; getting sufficient food and drink to satisfy hunger and thirst; eating daily a perfumed Tambula, _i.e._, a mixture of betel nut and betel leaves; and wearing ornaments gilt with gold. The Sages say that these represent the gains of all the middle and lower classes of courtesans, but Vatsyayana is of opinion that their gains cannot be calculated, or fixed in any way, as these depend on the influence of the place, the customs of the people, their own appearance, and many other things.
