When there are two lovers, one of whom is attached to the courtezan, and the other is simply very generous, the Sages say that a preference should be given to the generous lover, but Vatsyayana is of opinion that the one who is really attached to the courtezan should be preferred, because he can be made to be generous, even as a miser gives money if he becomes fond of a woman, but a man who is simply generous cannot be made to love with real attachment. But among those who are attached to her, if there is one who is poor, and one who is rich, the preference is of course to be given to the latter.
