Nagaland, India. Renowned for their former head hunting practices, the Nagas aren't cannibals nor really head hunters, but rather more like soul collectors. As early anthropologists explained, historically every Naga village was a “self-contained reservoir of the soul-force” called aren. Aren made the crops flourish and children multiply. A rich man had a particularly large supply of it, as did unusually strong boys and attractive girls. Aren is contained in the soul and the soul is in the head, so therefore the way to increase the collective supply of aren in one village was to obtain heads, and with it the souls, from other villages. Severing the head of a fallen enemy was considered an essential rite of passage for young Naga boys, and success was rewarded with prestigious facial and chest tattoos as well as distinctive ornaments such as hair, shells, animal teeth and necklaces made of bronze skulls - once for each head hunted - which, in turn, gave them higher status in the tribe. After head hunting was outlawed in the 19th century and Baptist missionaries became particularly successful in the area, most head hunting relics were burned or buried. As a result, for many Nagas, the only remaining artifacts of their head hunting days are the fading tattoos on the faces and chests of the aging Naga warriors.
