Bhagavad Gita Chapter 2 Verse 44

bhogaiśvaryaprasaktānāṃ tayāpahṛtacetasām
vyavasāyātmikā buddhiḥ samādhau na vidhīyate

For, those who cling to joy and Lordship, whose minds are drawn away by such teaching, are neither determinate and resolute nor are they fit for steady meditation and SAMADHI.

bhoga = to material enjoyment; aiśvarya = and opulence; prasaktānāṃ = for those who are attached; tayā = by such things; apahṛtacetasāṃ = bewildered in mind; vyavasāyātmikā = fixed in determination; buddhiḥ = devotional service to the Lord; samādhau = in the controlled mind; na = never; vidhīyate = does take place.;
