Service for Krsna should not be accepted as profession for livelihood. It should be simply for the service of the Lord. For the service of the Lord you can collect millions of dollars, but for your livelihood you cannot take one dollar from any person. Then you'll be indebted. You have to repay him. You cannot cheat others. It is very strictly enjoined.
