The sincere devotee of the Lord is always praying for the opportunity to satisfy the Lord and is praying for the opportunity to satisfy others by helping them to increase their attachement to the service of the Lord, because otherwise there is no other way to satisfy anybody in this material world. They may get some flickering pleasure, some material reward, material achievement. But in the heart there will always be something lacking.
