The Kama Sutra, or Aphorisms on Love, has survived at least 1400 years as a dominant text on sexual relations between men and women. Vatsyayana claimed to have written the Kama Sutra while a religious student, "in contemplation of the Deity" - but references to older works, shrewd disputations by Vatsyayana of those authors' recommendations, and careful cataloging of practices in various of the Indian states indicate much more emphasis on kama, or sensual gratification. Part of the book discusses the 64 arts of love employed by masters of coitus. Learning each of these and when and how to practice them, Vatsyayana affirms, not only leads to the best gratification, but makes the artist a person of great desirability.
