The article introduces to readers the activities of healers among the Finnish Orthodox people of Border Karelia (located on the northern shores of Lake Ladoga). The period discussed here focuses on the two decades between the First and the Second World War. The activities of healers consisted of finding and explaining a problem (usually the cause of an illness), and finding a solution. In Border Karelia, the most common explanations for an illness were that it had come from water, a forest or a graveyard. It was believed that all three were controlled by spirits, which the ill person had somehow offended, or, occasionally, which had been set on the ill person by somebody malicious. In both cases, the ill person’s share of limited good had diminished, and had to be enhanced. In the first case, the spirit(s) had to be conciliated. In the latter case, a counter-charm was needed.
