The sun has the ability to shine powerfully, and the moons reflect the sunshine and therefore look brilliant. In the Caitanya-caritāmṛta Kṛṣṇa is described to be like the sun. The supreme powerful is the Supreme Personality of Godhead Śrī Kṛṣṇa, or Lord Śrī Caitanya Mahāprabhu, and His devotees are also bright and illuminating because they reflect the supreme sun. The Caitanya-caritāmṛta (CC Madhya 22.31) states:

kṛṣṇa—sūrya-sama; māyā haya andhakāra

yāhāṅ kṛṣṇa, tāhāṅ nāhi māyāra adhikāra

"Kṛṣṇa is bright like the sun. As soon as the sun appears, there is no question of darkness or nescience." Similarly, the present verse also describes that by the illumination of all the moons, brightened by the reflection of the Kṛṣṇa sun, or by the grace of all the devotees of Caitanya Mahāprabhu, the entire world will be illuminated, despite the darkness of Kali-yuga. Only the devotees of Lord Caitanya Mahāprabhu can dissipate the darkness of Kali-yuga, the ignorance of the population of this age.
