Words attach themselves to mythological constructs in your brain. Mythology clouds. Clusters of brain activity that create meaning.
When I am in a deep, meditative state, I can actually watch a person formulate a word, a question, and see the web of clouds of interconnected thoughts, concepts, myths attaching to the word all of the emotional, mythological meaning- content that comes with that word or question. All of the moralizing, the good and evil of the content of that word actually attach to the word itself. That is how you know what a word means.
