It may be interesting to some persons to learn how it came about that Vatsyayana was first brought to light and translated into the English language. It happened thus. While translating with the pundits the 'Anunga runga, or the stage of love,' reference was frequently found to be made to one Vatsya. The sage Vatsya was of this opinion, or of that opinion. The sage Vatsya said this, and so on. Naturally questions were asked who the sage was, and the pundits replied that Vatsya was the author of the standard work on love in Sanscrit literature, that no Sanscrit library was complete without his work, and that it was most difficult now to obtain in its entire state. The copy of the manuscript obtained in Bombay was defective, and so the pundits wrote to Benares, Calcutta and Jeypoor for copies of the manuscript from Sanscrit libraries in those places. Copies having been obtained, they were then compared with each other, and with the aid of a Commentary called 'Jayamangla' a revised copy of the entire manuscript was prepared, and from this copy the English translation was made. The following is the certificate of the chief pundit:—

"The accompanying manuscript is corrected by me after comparing four different copies of the work. I had the assistance of a Commentary called 'Jayamangla' for correcting the portion in the first five parts, but found great difficulty in correcting the remaining portion, because, with the exception of one copy thereof which was tolerably correct, all the other copies I had were far too incorrect. However, I took that portion as correct in which the majority of the copies agreed with each other."

The 'Aphorisms on Love,' by Vatsyayana, contains about one thousand two hundred and fifty slokas or verses, and are divided into parts, parts into chapters, and chapters into paragraphs. The whole consists of seven parts, thirty-six chapters, and sixty-four paragraphs. Hardly anything is known about the author. His real name is supposed to be Mallinaga or Mrillana, Vatsyayana being his family name. At the close of the work this is what he writes about himself:

"After reading and considering the works of Babhravya and other ancient authors, and thinking over the meaning of the rules given by them, this treatise was composed, according to the precepts of the Holy Writ, for the benefit of the world, by Vatsyayana, while leading the life of a religious student at Benares, and wholly engaged in the contemplation of the Deity. This work is not to be used merely as an instrument for satisfying our desires. A person acquainted with the true principles of this science, who preserves his Dharma (virtue or religious merit), his Artha (worldly wealth) and his Kama (pleasure or sensual gratification), and who has regard to the customs of the people, is sure to obtain the mastery over his senses. In short, an intelligent and knowing person, attending to Dharma and Artha and also to Kama, without becoming the slave of his passions, will obtain success in everything that he may do."

It is impossible to fix the exact date either of the life of Vatsyayana or of his work. It is supposed that he must have lived between the first and the sixth centuries of the Christian era, on the following grounds:—He mentions that Satkarni Srtvahan, a king of Kuntal, killed Malayevati his wife with an instrument called kartari by striking her in the passion of love, and Vatsya quotes this case to warn people of the danger arising from some old customs of striking women when under the influence of this passion. Now this king of Kuntal is believed to have lived and reigned during the first century A.C., and consequently Vatsya must have lived after him. On the other hand, Virahamihira, in the eighteenth chapter of his 'Brihatsanhita,' treats of the science of love, and appears to have borrowed largely from Vatsyayana on the subject. Now Virahamihira is said to have lived during the sixth century A.D., and as Vatsya must have written his works previously, therefore not earlier than the first century, A.C., and not later than the sixth century A.D., must be considered as the approximate date of his existence.On the text of the 'Aphorisms on Love,' by Vatsyayana, only two commentaries have been found. One called 'Jayamangla' or 'Sutrabashya,' and the other 'Sutra vritti.' The date of the 'Jayamangla' is fixed between the tenth and thirteenth centuries A.D., because while treating of the sixty-four arts an example is taken from the 'KÁvyaprakÁsha,' which was written about the tenth century A.D. Again, the copy of the commentary procured was evidently a transcript of a manuscript which once had a place in the library of a Chaulukyan king named Vishaladeva, a fact elicited from the following sentence at the end of it:—

"Here ends the part relating to the art of love in the commentary on the 'Vatsyayana Kama Sutra,' a copy from the library of the king of kings, Vishaladeva, who was a powerful hero, as it were a second Arjuna, and head jewel of the Chaulukya family."

Now it is well known that this king ruled in Guzerat from 1244 to 1262 A.D., and founded a city called Visalnagur. The date, therefore, of the commentary is taken to be not earlier than the tenth and not later than the thirteenth century. The author of it is supposed to be one Yashodhara, the name given him by his preceptor being Indrapada. He seems to have written it during the time of affliction caused by his separation from a clever and shrewd woman, at least that is what he himself says at the end of each chapter. It is presumed that he called his work after the name of his absent mistress, or the word may have some connection with the meaning of her name.

This commentary was most useful in explaining the true meaning of Vatsyayana, for the commentator appears to have had a considerable knowledge of the times of the older author, and gives in some places very minute information. This cannot be said of the other commentary, called "Sutra vritti," which was written about A.D., by Narsing Shastri, a pupil of a Sarveshwar Shastri; the latter was a descendant of Bhaskur, and so also was our author, for at the conclusion of every part he calls himself Bhaskur Narsing Shastra. He was induced to write the work by order of the learned Raja Vrijalala, while he was residing in Benares, but as to the merits of this commentary it does not deserve much commendation. In many cases the writer does not appear to have understood the meaning of the original author, and has changed the text in many places to fit in with his own explanations.

A complete translation of the original work now follows. It has been prepared in complete accordance with the text of the manuscript, and is given, without further comments, as made from it.
