On wow. This thread has so many questions and thoughts running through my head right now but I’m not sure were to begin with them all.
I guess for starters, cjforJesus, did you know that even in Catholic asceticism Eastern and Western, poor souls have been lead astray, tricked,fooled, and I would even go so far as to say possessed by Lucifer to their own seemingly ruin or demise?
From the readings that people have shared on these forums of St. John and St. Theresa they warn consistently of how one can be tricked. In the Philokalia by St. Nikodimos of the Holy Mountain and St. Makarios of Corinth I read of this happening.
So I don’t see one being possessed by demons through working on acquired contemplation as being solely coming through other ancient practices of asceticism.
In my understanding the Catholic Church has the Complete Truth of what the purpose of contemplation and and quiet prayer the ascetic life is for and yes I do believe other forms of asceticism, some of which you speak of, and lead one to the fullness of this Truth if followed with a sincere heart of always seeking out the Truth. God works to save us through so much I would not but it past Him if He is leading them to the Fullness of the Truth of Asceticism that we have deposited in the Catholic Church through their ancient ascetic practices.
But what leaves one open to becoming possessed would be, to me, ones intent. And that is in any form or practice of asceticism.
Anyway just adding some food for thought here. Maybe I’m way off base here but I don’t think so, so I hope I have explained what I am seeing here well enough that it makes some sense.
