In Vātsyāyana’s Kamasutra (c. 3rd–5th century CE), Book 2 — Saṃprayoga (Amorous Advances) — systematically treats the art of sexual union. Drawing on earlier traditions, it catalogs embraces, kisses, timing, postures and rhythms, classifies lovers and compatibility, and advises on consent, foreplay and mutual pleasure. More than manual technique, Saṃprayoga frames kama within ethics, aesthetics and household life, linking sensual skill to harmony between partners. Historically influential in literature, anthropology and sexology, its measured, observational tone reframes desire as a cultivated human faculty. Today it remains relevant as a source of holistic sexual literacy: promoting intimacy, mutual respect, and the cultural understanding of love and pleasure across time.
