it was entirely my personal opinion about the matter . oh yes ! i know iskcon quite well .
on your question on 'criticism' , its iskcon who specialises doing that for socio religious organisations doing extensive charitable works . the explanation provided is that temporary feeding the poor might eliminate their hunger but would do nothing to make them realise the true cause of their suffering ( lack of krsna realization , that is) . thats all very good and fine . turning towards god is the highest goal of man , we know that . but what they seem to forget is that religion is a luxury for starving millions . its easy for people like us to sit back at the comforts of our home and speculate about dying children and hungry masses . perhaps its even easy to donate a months earning to such people . but fact remains that people like us with all modern comforts can never understand even a fraction of the pain they actually endures.
so when any financially strong religious organisation nominally approaches such helpless people with a subconcious motive of conversion and go on publicising such campaigns proudly world over it automatically draws comparison of similar other organisations who toil day and night with little or no funds without any self proclamation whatsoever.
once more it was my personal opinion.
