What is the meaning of But only words can free a thought From its prison behind your eye?

This line refers to the power of words to express and liberate thoughts. The thought is trapped within the confines of one's mind, like a prisoner behind bars. Only through words can the thought be released, shared with others, and gain freedom. Here's a breakdown of the line:

"But only words can free a thought": This part conveys the central theme. It suggests that words are the key to liberating thoughts.

"From its prison behind your eye": This phrase creates a metaphor comparing the mind to a prison. Thoughts are trapped behind the "eye," representing the innermost private realm of the individual.

The implication is that thoughts can be powerful, but they remain confined until they are expressed through words. By speaking, writing, or sharing, individuals can release their thoughts and allow them to be understood, explored, and developed by others. Ultimately, words have the power to break the barriers of the mind, letting thoughts flourish and have an impact on the world beyond one's own internal dialogue.
