Most people treat attention as a spotlight — you aim it, things get illuminated. But the 14th-century Flemish mystic Jan van Ruusbroec described something more unsettling: the untrained mind doesn't just miss things, it actively fills the gaps with its own noise, mistaking that noise for reality. Modern research on mind-wandering by Matthew Killingsworth and Daniel Gilbert found that the wandering mind isn't neutral — it tends to populate absence with worry, anticipation, and narrative. Ruusbroec called the remedy 'ledigheid' — a deliberate emptying that isn't passivity but a kind of alert receptivity, making space for what is actually present rather than what the mind habitually projects. The practical implication is precise: the goal of mindful attention isn't to concentrate harder, it's to stop manufacturing. Today, pick one conversation and notice where you begin composing your response before the other person has finished. That gap between their words and your listening is exactly where Ruusbroec and Killingsworth are pointing.

What would remain of your attention in a typical conversation if you subtracted everything you were already preparing to say?
