Alex, that's an interesting idea. Typically we don't recommend diving into too many Paraliminals at a time, because it is too easy to send yourself a message that you're trying to force change. The mind doesn't react favorably to forced change.
But! By calling it party you might just be playful enough to explore and see what happens without putting undo pressure on yourself.
Try it out. Let us know what happens. You might just be on to something.
I've heard of other Paraliminal Parties where a half dozen friends will get together with CD players and listen to Paraliminals together. Each will do a different Paraliminal.
In our retreats we've 100 people all listening to the same Paraliminal with headsets at the same time. The energy is palpable.
Has anyone else had a Paraliminal Party? If not try it out and share your experiences with us.
