There is no real happiness in the material world-- only temporary relief from suffering. The devotees are experiencing real happiness. And the more that they tolerate the nonpermanent appearance of material happiness and distress, and continue to serve despite all obstacles, the more they can sustain this real happiness. Krishna is waiting for us to turn to Him, and He wants nothing more than to fulfill all of our desires. Don't you forget that.
