In the game Warframe, we have blueprints which are "consumed" during the process of making a weapon / Warframe.
In some Chinese fantasy Kung Fu movies, a person caught illegally learning martial arts, i.e. stealing, from someone who has not agreed to teach him, can be punished by having his Kung Fu "banished" from him, making him no longer able to perform the skills.
In Dr Strange, at the post credits scene
Mordo "rips" something (I assume it's "astral knowledge") from Jonathan causing him to become paralyzed again.
If "blueprints", "Kung Fu", "astral knowledge" are just knowledge that can be recalled at any time, and if brainwashing does not occur (We don't see Ordis [The aforementioned Kung Fu stealer.] or Jonathan suffer any memory loss.), what would be a (pseudo-)feasible explanation of this?
