Become a Sun or Moon, Not a Star or Glowworm - Prabhupada Srimad-Bhagavatam Class 1.15.1 - Kirtan

We are unhappy because we are separated from Krishna. The modern philosophers or scientists may think otherwise. They try to improve the conditions in the material world. But that is not possible. We are unhappy because we are separated from Krishna.
Prabhupada concludes requesting his disciples to become like the sun or the moon, which are able to give actual valuable illumination, not to become like the useless stars and glowworms.
At the end there is Bhoga-Aroti kirtan followed by Gaura-Aroti kirtan.
