Bhagavad Gita 2.44
While their minds are absorbed with thoughts of power and personal enjoyment, they cannot focus their discrimination on one point.
भोगैश्वर्यप्रसक्तानां तयापहृतचेतसाम्।
व्यवसायात्मिका बुद्धिः समाधौ न विधीयते॥bhogaiśvaryaprasaktānāṃ tayāpahṛtacetasām|
vyavasāyātmikā buddhiḥ samādhau na vidhīyate||
