The Baudhāyana Dharmasūtra (3.7.2) says about ejaculation, "A man who ejaculates his semen in any place other than the vagina becomes equal to a thief, equal to a murderer of a Brahmin." For purification, the man should "get the hair of his head, beard, and body shaved and his nails clipped on a new-moon or a full-moon day" and observe a vow "for a year, for a month, or for twenty-four, twelve, six, or three days" not to "eat meat, engage in sex, or sit on anything above the floor, and recoil from uttering an untruth" (3.7.4–7).
