नास्ति बुद्धिरयुक्तस्य न चायुक्तस्य भावना। न चाभावयतः शान्तिरशान्तस्य कुतः सुखम्॥
nasti buddhir ayuktasya na chayuktasya bhavana na chabhavayatah shantir ashantasya kutah sukham
Translation
There is no wisdom for the unsteady, and no meditation for the unsteady. For one without meditation there is no peace, and without peace how can there be happiness?
Commentary
Krishna establishes a clear chain: self-discipline leads to wisdom, wisdom to meditation, meditation to peace, and peace to happiness. Without the first step, the entire chain collapses.
