From the descriptions in this verse, we can make an educated guess about the nature of the flames on the moon. Like the sun, the moon must also be full of flames because without flames there cannot be illumination. The flames on the moon, however, unlike those on the sun, must be mild and pleasing. This is our conviction. The modern theory that the moon is full of dust is not accepted in the verses of Śrīmad-Bhāgavatam. In regard to this verse, Śrīla Viśvanātha Cakravartī Ṭhākura says, suśaṣpāṇi sukomala-śikhās teṣāṁ rociṣā: the kuśa grass illuminates all directions, but its flames are very mild and pleasing. This gives some idea of the flames existing on the moon.
