Krsna takes special care of the devotee, guides him, gives him intelligence. What kind of intelligence? Yena mam upayanti te. Just to give him the clue how one can go back to home, back to Godhead. Krsna does not give intelligence how one can gain some material prosperity. That is entrusted to the maya — daivi maya or Durgadevi. Therefore people are not very much interested in worshiping Krsna.
