In order to fight black magic, you must have a spiritual awakening and live an experience of literally coming back from the dead. Specifically, to have a clinical death simulation for a day through meditation. There you are revealed the ultimate truth that not everyone can understand, including your origins. Go to hell and then heaven. But stay in heaven for a while, go to divine schools, and return to earth in your body with the ancestral teachings from God.
That's what I experienced.
