When a man and woman lie down in an inverted order, i.e., with the head of the one towards the feet of the other and carry on this congress, it is called the "congress of a crow."
For the sake of such things courtezans abandon men possessed of good qualities, liberal and clever, and become attached to low persons, such as slaves and elephant drivers. The Auparishtaka, or mouth congress, should never be done by a learned Brahman, by a minister that carries on the business of a state, or by a man of good reputation, because though the practice is allowed by the Shastras, there is no reason why it should be carried on, and need only be practiced in particular cases. As for instance the taste, and the strength, and the digestive qualities of the flesh of dogs are mentioned in works on medicine, but it does not therefore follow that it should be eaten by the wise. In the same way there are some men, some places, and some times, with respect to which these practices can be made use of. A man should therefore pay regard to the place, to the time, and to the practice which is to be carried out, as also as to whether it is agreeable to his nature and to himself, and then he may or may not practice these things according to circumstances. But after all, these things being done secretly, and the mind of the man being fickle, how can it be known what any person will do at any particular time and for any particular purpose.
