There are many who believe that the kundalini spirit has infiltrated the church masquerading as the Holy Spirit, and a lot of that is seen in Pentecostalism with the current *filled with the Spirit* phenomena of shaking and falling down.
Kundalini spirits in the church?

Interesting, whether its Kundalini or not matters little as a demonic influence is still demonic. It wouldn’t surprise me if that is what powers the Pentecostal movement though. As I already pointed out, Satan and his followers can appear as holy and good people. The speaking of tongues in the Bible was such that everyone could hear the disciples in their own language, rather than no one could understand the person who appears to be having a seizure.
