The `Aphorisms on Love' by Vatsyayana contain 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.'
The Kama Sutra contains a total of 64 sexual positions and depicts positions as arts. Vatsyayana believed there were eight ways of making love, multiplied by eight positions within each of these. In the book, they are known as the 64 Arts. The chapter listing sexual positions is the best-known, and a translation (different from Burton's) is in wide circulation on the Internet. This chapter was pirated from the 1980 translation of Indra Sinha and first appeared on the internet server wiretap.spies in the late eighties. It is commonly mistaken to be the entirety of the Sutra.

However, only about 20 percent of the book is devoted to sexual positions. The remainder gives guidance on how to be a good citizen and insights into men and women in relationships. The Kama Sutra describes making love as "divine union". Vatsyayana believed that sex itself was not wrong, but doing it frivolously was sinful. The Kama Sutra has helped people enjoy the art of sex at a deeper level and can be considered a technical guide to sexual enjoyment, as well as providing insight into the sexual mores and practices of India in those times

Kamasutram, generally known to the Western world as Kama Sutra, is an ancient Indian text on human sexual behavior, widely considered to be the standard work on love in Sanskrit literature. The text was composed by Vatsyayana, as a brief summary of various earlier works belonging to a tradition known generically as Kama Shastra, the science of love. Kama is literally desire. Sutra signifies a thread, or discourse threaded on a series of aphorisms. Sutra was a standard term for a technical text, thus also the Yogasutram of Patanjali. The text is originally known as Vatsyayana Kamasutram ("Vatsyayana's Aphorisms on Love"). Tradition holds that the author was a celibate scholar. He is believed to have lived sometime between the 1st to 6th centuries AD, probably during the great cultural flowering of the Gupta period.

The earliest text of the Kama Shastra tradition, said to have contained a vast amount of information, is attributed to Nandi the sacred bull, Shiva's doorkeeper, who was moved to sacred utterance by overhearing the lovemaking of the god and his wife Parvati.
During the 8th century BC, Shvetaketu, son of Uddalaka, produced a summary of Nandi's work. However this "summary" was still too vast to be accessible.
Modern translated version of the original Sanskrit.A scholar called Babhravya, together with a group of his disciples, produced a summary of Shvetaketu's summary. This remained a huge and encyclopaedic tome.
Between the 3rd and 1st centuries BC, several authors reproduced different parts of the Babhravya group's work in various specialist treatises. Among the authors, those whose names are known are Charayana, Ghotakamukha, Gonardiya, Gonikaputra, Suvarnanabha, and Dattaka:
— Dattaka composed a work on courtesans which Vatsyayana reproduces almost entirely in Kama Sutra.
— Suvarnanabha's text mentions Shatakarni Shatavahana, a king of the 1st century BC who killed his own wife accidentally during sadistic practices, thus giving a hint on the time period it was written.
Yashodhara, in his commentary of Kama Sutra, attributes the origin of erotic science to Mallanaga, the "prophet of the Asuras", meaning it originated in prehistoric times. Nandi is then said to have transcribed it for mankind. The attribution of the name "Mallanaga" to Vatsyayana is due to the confusion of his role as editor of the Kama Sutra with that of the mythical creator of erotic science.
