Don't wait for the mind to wander. Don't be having meditation. It's going too well. When will the mind start wandering? Mind, do your thing, don't do that. If it does not, doesn't matter the moment to recognize it, bring it back to the object of meditation. That's the yogic way. Also works for Buddhist mindfulness. But here in Vedanta, if you remember, there's an entirely different thing that we do. And that is, use the object of distraction to come back. You'd find this in Advaita Vedanta and Zogchen.
