William Shakespeare is considered the master of the human condition. That must mean all that a life encounters?
In Hamlet Act 3 the conditions of prayer, repentance, and perhaps murder are considered. Claudius wants to kill Hamlet who is watching a play and so he waits for a chance to do so. After the play Claudius goes to do his deed and overhears Hamlet praying. He hesitates and waits. He fears that being killed in the act of prayer, which may be like confession to God, would enable the person to go directly to heaven. Claudius leaves and Hamlet finishes his prayer and says these words:
"My words fly up, my thoughts remain below: Words without thoughts never to heaven go.
Is it just that prayer is often insincere? Is it that insincerity is judged by a God as He hears the words, or is it that the person knows as he prays that he doesn't mean it? He knows he didn't put much thought into?
What about words with thoughts? What does that really mean? How does that work? Is it enough, to have deep thoughts before speaking, to make what you say sincere? Does it take a lot of thought or is a certain amount of time required?
Maybe the human condition is one of primarily intent as far as getting your words "up" and heard? Are prayers offered to gain and forgiveness or to express sorrow?
These questions bring substance to the expression:
"words fly up".
Shakespeare seems to know that praying is something that needs some pondering.
