यतो यतो निश्चरति मनश्चञ्चलमस्थिरम्। ततस्ततो नियम्यैतदात्मन्येव वशं नयेत्॥
yato yato niścarati manaścañcalamasthiram tatastato niyamyaitadātmanyeva vaśaṃ nayet
Meaning
When the volatile and wavering mind wanders, let him restrain it and bring it back to its allegiance to the Self.
Simple meaning
Krishna gives a simple practice: whenever the restless mind wanders, gently bring it back. Not by force or frustration, just by returning again and again.
In real life
While studying, a student notices she has drifted to her phone. Instead of scolding herself, she calmly returns to the page. Over weeks her focus grows.
During meditation, a beginner's mind runs to office worries a hundred times. Each time he simply returns to his breath, and that returning is the practice.
Try this today: Set a 10-minute timer and focus on one task. Each time your mind wanders, note it and come back, without judging yourself.
