The quote from Kelley Armstrong's book "Visions" emphasizes the concept that true freedom cannot be attained unless individuals break free from their mental constraints. It highlights the idea that one's thoughts and perceptions can limit their experiences and sense of autonomy, creating a metaphorical prison. This suggests that self-awareness and mental liberation are essential for achieving genuine freedom.

In the context of Armstrong's work, this theme resonates with the struggles characters face as they navigate challenges both externally and internally. The narrative encourages readers to confront and overcome their mental barriers, advocating for the importance of a resilient mindset in the pursuit of personal freedom and fulfillment.
