Desire to Please Devotees
Just the desire to please the devotees by putting sincere efforts is pleasing to Krishna.
What Should We Be?
Be what you except others to be.
Shelter
Shelter comes when the Lord is pleased with our intention & spirit of service.
Cause of Suffering
If there is no enjoyment in this world, there would not be so much suffering. As suffering really is the frustration of our attempts to enjoy.
