The Kamasutra is an ancient Indian text attributed to the philosopher Vātsyāyana, dating back to the 3rd century CE. It is best known as a manual on sexual behavior and relationships, but it also covers various aspects of life, including love, marriage, and social conduct. The text emphasizes the importance of balance between spiritual, emotional, and physical connections in relationships. While often associated with eroticism, it offers broader insights into human intimacy and companionship.
