Maybe Some of the Indians have heard about "Voodoo Doll" pins, candle wax and many more. This could be a lot. So a voodoo doll is a doll shaped like a human body then you poke pins into the doll(as the doll is someone you hate/ditched/you think someone is bad to you) but a voodoo doll could also be used in a good way just by changing the colour of the pins. In ancient times, the Voodoo dolls have been used just to attack a person physically and mentally... and tbh it work...
