The charm lamp is generally placed upon a table at which the person performs the magical operations. It is usually made of half a coconut shell, and contains ingredients which have analogous qualities of sweetness and attraction: a magnet, syrup, sugar, honey, perfume and flower petals, particularly those of jasmine and heliotrope.
The chief constituent of the lamp is a sheeps brain purchased with the idea in mind of purchasing the individual whom one wishes to charm. Olive oil is added, and the lamp is lighted in the name of Legba, who represents the heart, and Erzulie, who represents the sentiment of love. It is kept lighted until results are obtained.
