What is black magic?

Friends, till yesterday science did not accept this but today it is forced to accept it.
The reason for this is that many such incidents happened which were beyond science. Even science accepted defeat. Science has accepted it today.
But people have been believing in it since ancient times and many people have also felt it very closely, hence we cannot deny its existence.
You must have heard or seen somewhere that suddenly all the circumstances change, whether it is time or humans. Or many situations suddenly become beyond our understanding. We are unable to understand why? How? When? Who? And we get confused.
Black magic, you should consider it as a name because it has different names in different countries. Actually it is a part of voodoo. In voodoo we activate the doll, in this we activate the photo, sometimes the doll also has to be activated, it will depend on the problem.
Like Vedic Tantra, it also has six actions (killing), (enchantment), (immobilisation), (subduing), (vashikaran), (extermination), (disillusionment), only the methods are different
