This relies on the pervasive effect of photographs, and is related to The Sugar & Salt Technique, and its manipulation of inverted energy patterns. It requires that you procure two photographs of yourself (taken at any time). You place them back to back, with the images inverted, so that the head on one is behind the feet (or bottom) of the other. It can be enhanced by placing a part of a fingernail or toenail between the photographs.
