HOW TO REMOVE BLACK MAGIC?

Yes, there is a science that allows one to harness their energy negatively to injure another person. What is the defence? One thing is that if you are engaged in spiritual practise, you do not need to worry about any of those things. You don't even need to consider those things. Another option is to wear certain defences, such as a rudraksha, which functions as protection against all forms of negativity. However, you don't need to be concerned about them. Just keep moving forward in life and remain focused. If you are engaged in a black magic, you should just not worry about it.
