Everyone should appreciate the value of other devotees. Nobody should criticize anyone. Because everyone is engaged in the service of the Lord, according to one's capacity, and the thing is, Krishna wants to see how much one is sincere in rendering Him service. Materially we may think that his service is greater than his, that is our material vision.
- Srila Prabhupada
