A very versatile spell that I have found very useful is the Honey Pot. This spell is quite flexible, no honey? brown sugar is a traditional substitution. I think anything sweet and special will do, really. You put the sweet stuff in the pot or jar or box and add other spell components of significance, identifying information for the target of the spell, and candles (maybe dressed with oil) to burn on top while focusing on the spell, perhaps at special times or days (moon phases, days of the weeks, planetary hours, if you are into any of those things).
If there is a situation you need to sweeten up, this is a very straightforward way to do it and it has worked very well for me. I am having trouble researching it as the same information is just plagiarized over and over all over the net. This spell is traditional in hoodoo, but I believe it has cognates in other traditions. Does anyone know of similar spells in other traditions?
