"When an unclean spirit goes out of someone, it
roams through arid regions searching for rest but, finding none, it says, 'I
shall return to my home from which I came.' But upon returning, it finds it swept clean and put in
order. Then it goes and brings back seven other spirits more wicked than itself who move in and dwell there, and the last condition of that person is worse than the first." (Lk 11:24ff)
The vacuity of such endeavor will quickly be filled, as Our Lord warns (above), with the spiritual entities that C. S. Lewis warned of in his book, That Hideous Strength, and mortals had best steer clear of. Selah.
