Meaning of this quote? "The fish trap exists because of the fish; once you’ve gotten the fish, you can forget the trap"?

What is done is done. Move on.

It seems like a quote from Chuang Tzu which goes on to say “words exist because of meaning, once you’ve gotten the meaning, you can forget the words.”
It is an analogy. As the fishtraps sole purpose is to catch fish so the only purpose of words is to communicate meaning. Once you fully absorb the meaning the words are superfluous.

Thanks @flutherother was making sure I didn’t miss anything. Nice quote.

It seems that it is related to the statement, The end justifies the means.
