When something meaningful and perhaps even revelatory happens without any apparent cause, we call that a coincidence. Afterward, we’ll say it came “out of the blue,” meaning out of the depths. For every coincidence we recognize, there are a million we don’t. Everything belongs.
Our thoughts and feelings are completely unbidden. We don’t say, ‘Now I’m going to worry for 20 minutes,’ and then do just that. Our thoughts and feelings cannot be controlled. They happen to us. And then something untoward occurs. We get attached to them.
