This is an outstanding documentary by Andrew Strom called False Spirits Invade the Church- Kundalini Warning. Just because something is popular, and big in crowd numbers in church service doesn't mean that the Spirit of God is behind it. What were seeing is the rise of false prophets, and people following these false revivals are being given over to doctrines of devils that is deceiving the masses. We need to be able to spiritually discern what is the Spirit of God and what is demonic in nature.
Matthew 24:11 False Prophets Arising
1 Timothy 4:1 Doctrines of devils & seducing spirits
1 Peter 5:8 Being sober and vigilant
