According to Osho, keep attention anchored to the breath. Mind will slip - do not chase wandering thoughts or fight them. Simply check: On the breath, or not? If not, gently return; if yes, rest there. Allow lapses without anxiety; repeated, effortless returning retrains the mind's old habit and presence stabilizes over time.
When your mind wanders, just notice it and gently bring your attention back to your breathing without chasing or resisting.
