नास्ति बुद्धिरयुक्तस्य न चायुक्तस्य भावना । न चाभावयतः शान्तिरशान्तस्य कुतः सुखम्

nāsti buddhirayuktasya na cāyuktasya bhāvanā na cābhāvayataḥ śāntiraśāntasya kutaḥ sukham

Without inner discipline there is no stable wisdom, without wisdom there is no real meditation, without meditation there is no peace, and without peace there is no happiness.
