Cledons
"One of the most ancient forms of divine guidance is called a cledon. A cledon is a voice the crowd. They are words or phrases seemingly heard at random or out of context, spoken by a stranger or passerby, but their precise timing delivers a message of profound personal meaning to the hearer. In the modern world we are likely to heard cledons coming from a radio as we are walking down the street, or see them on a television screen as we channel surf, or even read them on a billboard or bus ad. There's a cledon story about John Lennon that I find very moving. In December 1980, right after John had been shot, a man ridiculed the grieving kids at the Dakota, ending his diatribe with "I fought the war for your sort!" - a line from A Hard Day's Night, obviously unbeknownst to him. The crowd, recognizing their cue, spontaneously shouted in unison John Lennon's comeback from the movie: "Bet you're sorry you won!" The man, shocked, muttered and walked away and the kids foudn themselves laughing, certain that this was John's way of cheering them up.
Cledons are one of my favorite methods of divinatory guidance because they catch me by surprise, often make me laugh, and always make me marvel at the ingenuity and genius of the universal consciousness. You can't really create a cledon, or practice a cledon, as you would practice other forms of divination. It is, by its very nature, spontaneous. But we can pay attention so we don't miss them! "
