Black Magic is a usage of supernatural powers for evil and selfish purposes and to perform malicious practices to destroy someone physically or mentally or financially. It can be done using the victim's hair, clothes, photo or looking directly into eyes. Practicing black magic is not something new, it has been practiced for generations and hence we need to be very careful in this time of Kalyug where you are surrounded by very few well-wishers.
Individuals with weak horoscopes or having malefic positions of planets in horoscopes are easy targets of black magic as they have weak aura around themselves. Some basic symptoms like disturbance in sleeping, bad dreams like falling from heights, darkening of complexion, headaches, eccentric behaviour, etc.
Black magic makes humans victims of baseless fears, reverses fortune and creates confusion.
I do deal with such issues and help my clients remove the negative energies by doing various types of healings and remedies.
