Again, it is believed that a man who has been on a journey may have contracted some magic evil from the strangers with whom he has associated. Hence, on returning home, before he is readmitted to the society of his tribe and friends, he has to undergo certain purificatory ceremonies. Thus the Bechuanas "cleanse or purify themselves after journeys by shaving their heads, etc., lest they should have contracted from strangers some evil by witchcraft or sorcery." In some parts of Western Africa, when a man returns home after a long absence, before he is allowed to visit his wife, he must wash his person with a particular fluid, and receive from the sorcerer a certain mark on his forehead, in order to counteract any magic spell which a stranger woman may have cast on him in his absence, and which might be communicated through him to the women of his village. Two Hindoo ambassadors, who had been sent to England by a native prince and had returned to India, were considered to have so polluted themselves by contact with strangers that nothing but being born again could restore them to purity. "For the purpose of regeneration it is directed to make an image of pure gold of the female power of nature, in the shape either of a woman or of a cow. In this statue the person to be regenerated is enclosed, and dragged through the usual channel. As a statue of pure gold and of proper dimensions would be too expensive, it is sufficient to make an image of the sacred _Yoni,_ through which the person to be regenerated is to pass." Such an image of pure gold was made at the prince's command, and his ambassadors were born again by being dragged through it.
