There is example in the Bhagavata that in the rainy season, when the sky is covered with clouds, the glowworms become very prominent. Glowworms. But when the sky is clear, there is moonshine, these glowworms have no meaning. So in the world there are so many glowworms, because real knowledge is covered. They do not know — they have forgotten what is Krsna; therefore all these this rascal glowworms are prominent.

But this movement is clearing the clouds, bringing out the moon, sreyah-kairava-candrika-vitaranam.

There is no use any more of the glowworms. Caitanya-candrodaya, the rising of the moon of Lord Caitanya. Caitanya-candrodaya. Now He is rising gradually, just like moon rises gradually and one day becomes full moon. Similarly, Sri Caitanya’s movement is rising gradually, and one day it will
clear the sky and all these glowworms will go away.
