This is a Vashikarsn Mantra which is normally used by Tantriks to bring a woman under their spell of attraction.
The procedure to practice this Attraction Mantra is thus-
On any Saturday you have to take the dust from beneath the foot of a woman [that is the dust from the spot where the woman was standing].
You have to get some hair of that particular woman.
Then you have to prepare a doll and apply the hair and dust to that doll.
Then you have dress that doll in a dress made from blue colored cloth.
Then you have to apply some of your semen on the place where you perceive the vagina of that doll could be.
Then apply some Sindoor [red colored powder or paste of Vermilion applied by married Hindu women on their foreheads] on the vagina of that doll.
After following the above procedure you have to hold that doll in your hand and recite this Mantra 21 times, this will bind that doll with the mantra. The word amuki [ अमुकी ] has to be replaced by the name of the woman.
Then you have to bury that doll on the left side of the house of that woman.
When that woman crosses the spot where you have buried the doll, she will come under your spell of attraction.
