Translation

In the minds of those who are too attached to sense enjoyment and material opulence, and who are bewildered by such things, the resolute determination for devotional service to the Supreme Lord does not take place. 

Commentary by Srila Prabhupada 

Samadhi means “fixed mind.” The Vedic dictionary, the Nirukti, says, samyag adhiyate ’sminn atma-tattva-yathatmyam: “When the mind is fixed for understanding the self, it is said to be in samadhi. ” Samadhi is never possible for persons interested in material sense enjoyment, nor for those who are bewildered by such temporary things. They are more or less condemned by the process of material energy.

Commentary by Sri Visvanatha Cakravarti Thakur

Those whose minds are attracted by the flowery words, who are attached to power and enjoyment, do not have the determined intelligence fixed firmly on one point (samadhau), on only the Supreme Lord. The form of the verb na vidhiyate is reflexive passive (karma kartari), meaning in this case "is not attained." This commentary is Sridhara Swami's version.
