I ask you guys for help

Hello, I'm Brazil, and I have a deep desire to practice the goetia system but I don't know where to start I've read some books but apparently they hide some secrets I've seen some videos that say that the artifacts go through consecration and not all the materials are mentioned or artifacts necessary for the practice, it is said that the protection circles that are sold do not have one of the names of protection for the magician. With this in mind, I come here humbly to ask for your help so that you can provide me with a direction so that I can follow and start practicing the system.
