Acts 8:5-13 Simon used sorcery

⁵ Then Philip went down to the city of Samaria, and preached Christ unto them.

⁶ And the people with one accord gave heed unto those things which Philip spake, hearing and seeing the miracles which he did.

⁷ For unclean spirits, crying with loud voice, came out of many that were possessed with them: and many taken with palsies, and that were lame, were healed.

⁸ And there was great joy in that city.

⁹ But there was a certain man, called Simon, which beforetime in the same city used sorcery, and bewitched the people of Samaria, giving out that himself was some great one:

¹⁰ To whom they all gave heed, from the least to the greatest, saying, This man is the great power of God.

¹¹ And to him they had regard, because that of long time he had bewitched them with sorceries.

¹² But when they believed Philip preaching the things concerning the kingdom of God, and the name of Jesus Christ, they were baptized, both men and women.

¹³ Then Simon himself believed also: and when he was baptized, he continued with Philip, and wondered, beholding the miracles and signs which were done. -Acts 8:5-13 Bible, King James Version

There are white magicians and black magicians. Black magicians can only operate in the lower worlds which are associated with the human state of consciousness because in the Higher Planes of Divine Consciousness there is only the Light and Love of God so no darkness can exist there. It is, I believe, important to realize that black magic is practiced by thinking or feeling negative thoughts and emotions therefore we need to control our thoughts and feelings so they are only positive. Remember the Law of the Harvest, or the Law of Karma, which means that whatever we do to others will eventually be done to us.
