Write the name of the person on a piece of parchment/paper.
Fold it twice.
Take a lime and cut it twice, once
diagonally and once horizontally, but don't cut it all the way into four
Place the paper or parchment inside the
lime and hold it together with two long steel nails.
Place the lime into a clean glass jar and put
into it some ash, salt and vinegar and screw the lid on tight. Keep the
jar in a secure place where other people won't see it.
When you no longer have need of the jar,
pour the contents onto the ground and then recycle the jar.
The ash and salt are supposed to thwart
their efforts to cause you trouble of any kind, and the vinegar and lime
should sour their own affairs at the same time.
