I am so pleased with you that you have done so nicely in the service of the Lord to your best capacity. That is required. It is not that everyone should be equally expert. But the thing that is needed is that we should be serious and sincere in our engagement. Nobody can adequately serve Krishna because Krishna is unlimited. But Krishna so kind that even a small leaf or flower offered to Krishna by the poorest man in the world, Krishna accepts such thing. Krishna is so opulent that he is not even slightly benefited by any presentation but he is so kind and merciful that he accepts a little bit of leaf or flower or water from his devotees, and because a devotee comes to him with such love and affection he becomes very much satisfied.
