Some things happen whether we want them to or not. They are life's surprises and result in things we are compelled to do.
To seek healing or suffer as circumstances worsen is that compulsion. A choice.
Dementia, mental illness and yes even possession can happen around one. It draws down and aids darkness though the first two are not evil of themselves. Darkness tries to utilize them and distract from wellness. Wellness dispels darkness.
Nolens volens can be mild or severe, even good or bad.
We may know when things happen. There are warnings and usually increasing signs. But, ignoring something will NOT make it go away.
One might hope and see periods where things seem better. But, sooner or later the problem manifests and to a crescendo and leaves no doubt as to intense problems.
What are we gonna do?
Find trustworthy people, get advice from those who are skilled.
Don't let negativity take you with it.
Seek healing and help for self to deal with those who will not.
Nolens volens is an old story.
Prepare for the unexpected.
