So you are saying this "impartation" of the Toronto Blessing and the manifestations seen in these videos isn't so much a manifestation of the Holy Spirit, but a manifestation of demonic forces leaving the body, as in an exorcism?
That's not how these Pentecostals describe it.
I can't speak for the Pentecostals : ) And as I said, I don't know if this is the actual Kundalini process in these videos. That's between these people and God.
But what I am saying is that (among other things) Kundalini effects purification which, at fundamental stages, can function as an exorcism (if any evil entity needs to be driven out), but also addresses psychological and moral weaknesses as well, which generally take far longer to deal with.
And real Kundalini always creates genuine spiritual purification. It changes people from pursuing darkness, to living in light. From being attracted to perversions, to being attracted to what is generally referred to as "clean living." And then on to deeper and deeper love for God and God's moral law. Anything, therefore, called "Kundalini" that leads to the spiritual worsening of someone is not Kundalini.
But consider - if the purifying power of God, the Holy Spirit, is One and Only, then while it acts in the same way, other cultures would name it differently. But it's effects would always be spiritual purification, never destruction. Yet free will would likewise never be destroyed. So in every culture there have been "falls from Grace" - but that isn't Grace's fault.
