“Spiritual” techniques that actually work thread

This thread is for:

- Perfectly natural and functional ideas that came from a spiritual, religious, occultist, parapsychologist etc. source (perhaps with some “baggage”)

- Techniques that are bit difficult to explain and may be seen by the gullible as magic, but they actually seem to do something, even if that something is just a novel way to trick the brain.

Both things that are actually useful and “stage tricks” are accepted in this thread.
