Which was the world- famous treatise of the amorous arts?

The Kamasutra is an ancient Indian Sanskrit text on sexuality, eroticism and emotional fulfillment in life. Attributed to Vatsyayana, the Kama Sutra is neither exclusively nor predominantly a sex manual on sex positions, but written as a guide to the "art-of-living" well, the nature of love, finding a life partner, maintaining one's love life, and other aspects pertaining to pleasure-oriented faculties of human life.
