Bharyadhikarika (on one's own wife).
5th.

Paradika (on the wives of other people).
6th.

Vaisika (on courtesans).
7th.

Aupamishadika (on the arts of seduction, tonic medicines, etc.).
The sixth part of this last work was separately expounded by Dattaka at the request of the public women of Pataliputra (Patna), and in the same way Charayana explained the first part of it.

The remaining parts, viz., the second, third, fourth, fifth, and seventh were each separately expounded by-- Suvarnanabha (second part).
Ghotakamukha (third part).
Gonardiya (fourth part).
Gonikaputra (fifth part).
Kuchumara (seventh part), respectively.
Thus the work being written in parts by different authors was almost unobtainable, and as the parts which were expounded by Dattaka and the others treated only of the particular branches of the subject to which each part related, and moreover as the original work of Babhravya was difficult to be mastered on account of its length, Vatsyayana, therefore, composed his work in a small volume as an abstract of the whole of the works of the above-named authors.
