My Father got into that when he was younger same as you, he saw it in a magazine and later called to get their book. It wasn't till 5-10 years later that he learned that Rosicrucians are nothing more than another cult. Another Luciferian cult. It was satanic and demonic in nature. He studied it for a while and that was what he discovered. He warned me never to get involved with that. He said they make it seem innocent until you get deeper. And are asked to call upon your spirit guides or masters. Which are nothing more than demonic pieces of trash. Be careful what you get yourself into. From what he told me he actually got to see one of these beings while looking in a mirror. He said they were evil beyond words. After he had his experience he grabbed the book and burned it. He came to God and asked for forgiveness. He knows beyond all doubt the spiritual realm is real.
