I Want your blood!!! lol jk
if you really want dirty and grimmy and wish to live with the guilt and karma then here you go.
one jar with lid
papper with name of target or picture of target
your own urine
fill the jar with you urine, drop the papper or pic in the jar with lid, then hide jar away from you house and a place where it wont be found any time soon
dont keep this around or near you because of the strong negative energy can bring you down and attract alot more negative energgies and entities. urine has played a huge role in maney culturs as toxic and vile and the same should happen to the target,
if you can live with ruining a life and not care that karma will come to collect then so be it.
