How do I use mindfulness to break patterns of overthinking and rumination?

Overthinking is a loop—your mind rehearsing scenarios, searching for certainty it can never find. Patanjali identified this as "vritti," the mind's tendency to create endless variations on the same worry. The question isn't how to think less. It's how to interrupt the loop itself. Mindfulness breaks this by anchoring you in what's actually happening right now. When you're caught in "what if" spirals, those what-ifs exist only in your mind, in the past or future. Your breath exists now. Your feet on the ground exist now. When you notice rumination starting, that awareness itself is the intervention. Here's the practical shift: Instead of fighting the thoughts or trying to force them away—which ironically strengthens them—you notice them like clouds passing. "There's the worry about the meeting. There's the replay of what I said yesterday." You name the pattern without judgment. This sounds simple because it is, but it requires practice. Patanjali taught that mastery comes through "vairagya"—a kind of non-attachment, not indifference but freedom from being controlled. When you can observe your rumination without being pulled into it, the loop loses power. Start small: catch yourself mid-spiral once a day. Notice it. Breathe. That's progress. The mind's nature is to wander; your job is to notice gently and redirect, again and again.
