The Yantra shown in the image has to be drawn using any kind of ink or pen on a leaf of a Kaner Tree, commonly called as the Oleander Tree in the English language.
|Dushman Ko Sar Dard Dene Ka Yantra|
Once prepared, the Yantra should be kept on the ground and the Spell Caster should take the name of the enemy, whom he wishes to give a Headache with intensity and hammer a Nail into the Yantra.
That is all that has to done as per the Tantra, which says that this will make the enemies head start aching severely and distract his mind and stop him or her from bothering the Spell Caster.
Note- this is an out and out Tamas-Guni Yantra Experiment and should only be used for protective purposes to divert the attention and concentration of an enemy and stop him from troubling you.
There is no infusing/energizing procedure for this Yantra.
