There are remedies available which not only removes the negative effect of Black magic but prevents it from coming back. This is done by energising either a Maran yantra. If you do not have a Maran Yantra then you can use betel nuts which can be purchased from any Indian grocery shops. The betel nuts must be washed and dried. You can use 21 betel nuts and put them in a small silver vessel. Maran mantras need to be recited on the yantra or the silver vessel. The amount of mantras depend on how strong you want the remedies to be. The longer it takes the stronger it becomes. If Maran mantras are not accessible then Kali Mantras can be used. Once the mantras are finished then these have to energised by fire. Even during Shiva and Parvati times, it was the female energy of Kali which destroyed the demons. Because we are in Kali yuga the dark energy becomes very strong and to counter this energy, equally strong remedies are necessary. The remedies have to energised at least 9 times
