When we attune ourselves to the breath, the mind becomes empty.
" Mind becomes empty! It has never happened to me." During meditation, thoughts are always crossing our minds. Maybe for some saints, who have meditated for years, a state appears when there are no thoughts. But for a beginner or layman like us. As long as we don't get attached to these thoughts, let them fly off then the mind is as good as an empty mind. Continue observing our breath.
Keep Meditating
