This treatise has been composed by one who, resenting the misrule of the Nanda kings, rescued this neglected science and used it as a weapon to destroy them and save the kingdom. By following [the principles set out in] this treatise one can not only create and preserve dharma [spiritual good], artha [material well-being] and kama [aesthetic pleasures] but also destroy [their opposites, i.e.] unrighteousness, material loss and hatred. It is a guide not only for the acquisition of this world but also the next. {15.1.73,72,71}
