A devotee needs an opportunity to serve Krishna. If he has that opportunity to serve, he is so satisfied by that service that he can be satisfied in any condition of life. That is the difference between a devotee and a nondevotee. A devotee is one who is satisfied with whatever the Lord provides for him. We see this in the example of Suklambhara. He did not know the meaning of the word poverty, even though all he ate every day was a few grains of broken rice. Suklambhara never felt impoverished; he was satisfied because the Lord was reciprocating within his heart.
