As a kid, I used to lie in bed at night, thinking. I’d imagine things, tell myself stories, or replay the day’s events. Eventually it would be late enough that even my kid brain worried I’d be tired the next day, and I would tell myself to stop thinking and try to sleep.
The thing that usually tipped me off that I’d been “daydreaming” too late into the night was suddenly becoming aware of my current thought, and realizing I had no idea how I’d gotten there. When this happened, I’d play a game of retracing my mental steps before falling asleep. It would go like this:
“… velociraptor, that is definitely the best dinosaur. Wait why am I thinking of dinosaurs? I was thinking of basketball practice tomorrow.”
“… dinosaurs, which came from velociraptor, which came from Toronto Raptors … Vince Carter … I wish I could dunk … basketball practice tomorrow.”
Today I was reminded of how I used to play this mental retrace game. I was listening to my meditation app, and the guest teacher Joseph Goldstein retold a Buddhist proverb that compares the untrained mind to a waterfall, always tumbling down. The metaphor that’s more common in Western speech, he continued, is the train. We lose our ‘train of thought’ all the time, which can happen only when we’re identified with (lost in) thought, rather than observing thought. When our minds wander, Goldstein says, it’s like “hopping on a train, and never knowing the next stop,” or even like “falling asleep on a train and then awakening, not knowing where you are or how you got there.”
Awakening is the practice of breaking the spell, realizing you were lost in thought, and no longer being identified with thought. It was fun to remember back to being a kid, and realize that many nights lying alone, I’d been doing something like meditation practice, without knowing it.
