At the moment there is none. There are a lot of people selling some kind of vessel namely magical vessels and protection vessels, claiming that those have gone through some type of magic spells and rituals to ward off demons. As far as I am concerned, none of those will work. Before I became what I am now I was very curious about the Spiritual world, magic, and paranormal objects. I have spent literally thousands of dollars purchasing those vessels in the forms of rings, stones, crystals, figurines, and more from many, many different metaphysical sellers and learned the hard way that none of those really work. No regrets because that was a process of learning and realization to build me up energetically. Now that I work for God, I don’t get fooled by such items and claims. Crystals can be of help to cleanse a small area of low vibrational energies and give you some effect when used to meditate…etc.
The good news is that God told me that in the future Demons will no longer be able to influence Humans. I wasn’t given the exact time period when that will come but I am thankful to God to know it. I was given the title “Demon Killer” and a “Soul Healer” by God and I get demonic attacks. I have learned the only way to completely be protected from Demons is to build yourself up Energetically. I need to grow stronger energetically as well. Many clients of mine, in fact, all of them, asked me if there is a way to keep free of Demons, and each time I explained what I have written above to each and every one of them. If such a method or thing actually exists I would be the first one to grab it!
