If you're talking about the kundalini/holy spirit/soul/Epinoia/Daughter of Ruha then yes, it is basically demonic possession in itself as well as opening you up to possession by actual external entities.

If you're talking about seed of Seth/Typhon//Son of Adamas then it is what most people think is demonic possession, but is actually the opposite and protects you from it. If you think that though, as a skeptic to anything I read/hear then I acknowledge your opinion, but personally disagree.
