The procedure for conception

The husband keeps away from the woman for three days; on the fourth day she bathes, adorns herself auspiciously and eats well, including warm khichdi with oil, while he eats food rich in ghee, milk and jaggery (the commentary adds sugar) with plenty of aphrodisiac fare, adorns himself and, with a glad mind, goes to her at night. If they wish for a son, she lies on her right side for one muhūrta afterwards; for a daughter, on her left.
