(a). When a courtesan can get money from a man whom she may go to see, and also money from a man whom she may not go to see, this is called a gain on both sides.
(b). When a courtesan has to incur further expense if she goes to see a man, and yet runs the risk of incurring an irremediable loss if she does not go to see him, this is called a loss on both sides.
(c). When a courtesan is uncertain, whether a particular man would give her anything on her going to see him, without incurring expense on her part, or whether on her neglecting him another man would give her something, this is called a doubt on both sides about gain.
(d.) When a courtesan is uncertain, whether, on going at her own expense to see an old enemy, he would take back from her what he may have given her, or whether by her not going to see him he would cause some disaster to fall upon her, this is called a doubt on both sides about loss.
By combining the above, the following six kinds of mixed results are produced, viz.:
(a). Gain on one side, and loss on the other.
(b). Gain on one side, and doubt of gain on the other.
(c). Gain on one side, and doubt of loss on the other.
(d). Loss on one side, and doubt of gain on the other.
(e). Doubt of gain on one side, and doubt of loss on the other.
(f). Doubt of loss on one side, and loss on the other.
A courtesan, having considered all the above things, and taken council with her friends, should act so as to acquire gain, the chances of great gain, and the warding off of any great disaster. Religious merit and pleasure should also be formed into separate combinations like those of wealth, and then all should be combined with each other, so as to form new combinations.
When a courtesan consorts with men she should cause each of them to give her money as well as pleasure. At particular times, such as the Spring Festivals, etc., she should make her mother announce to the various men, that on a certain day her daughter would remain with the man who would gratify such and such a desire of hers.
When young men approach her with delight, she should think of what she may accomplish through them.
The combination of gains and losses on all sides are: gain on one side, and loss on all others; loss on one side and gain on all others; gain on all sides, loss on all sides.
