If you try to quiet your mind then of course it will dominate, because you’re trying to quiet your mind, which is just another form of chasing after it. Don’t worry about whether your mind is noisy or quiet, just do your practice — counting your breaths, mantra, great question, whatever your practice is…. Do your practice with a noisy mind. Do your practice with a quiet mind. Doesn’t matter. Just keep doing your practice. Do your practice and stick to the same practice. Don’t jump around from practice to practice. For days, weeks, months, years. Sure your mind will jump around. Just don’t follow it. On its own, your mind will start to quiet down. It will start up again. It always does. But you don’t have to follow it. That’s the point.
It’s exactly in the exercise of not checking the quality of our mind — is it noisy? is it quiet? — not getting trapped by our thoughts, it’s in the exercise of just doing our practice, that we have an opportunity to discover our true self, our true nature, which is more fundamental than all that activity in our frontal lobes.
