To "mind****" means to systematically lie with intent to profit, often involving creating the impression that the deceived one will gain some good from it.
The deception is not discovered till its way too late. Some people even die having never realised the lie (eg the Red Barn cult.)
The process of recovery from a mind**** may require professional help, and typically involves intense and disturbing emotion, such as shock, confusion, or fear.
Researchers now say that any ordinary person can be conned in this way; one does not have to be especially gullible or naive because the perpetrators are highly skilled at what they do.
Have you ever had an experience like this? If so, how did you recover?
If you have avoided one or more - how did you recognise the signs?
Did you tell the person (or group) what you honestly thought?
Did you blow the whistle?
