Moon

Of the Ādityas I am Viṣṇu, of lights I am the radiant sun, of the Maruts I am Marīci, and among the stars I am the moon.
(BG 10.21)

I enter into each planet, and by My energy they stay in orbit. I become the moon and thereby supply the juice of life to all vegetables.
(BG 15.13)

I offer my respectful obeisances unto Śrī Kṛṣṇa Caitanya and Lord Nityānanda, who are like the sun and moon. They have arisen simultaneously on the horizon of Gauḍa to dissipate the darkness of ignorance and thus wonderfully bestow benediction upon all. Śrī Kṛṣṇa and Balarāma, the Personalities of Godhead, who formerly appeared in Vṛndāvana and were millions of times more effulgent than the sun and moon, have arisen over the eastern horizon of Gauḍadeśa [West Bengal], being compassionate for the fallen state of the world.
(CC Adi 1.84 – 86)

Tad-bhāvādhyaḥ samajani: “He appeared in the womb of mother Śacī.” Samajani śacī-garbha-sindhau harīnduḥ. Hari, the Supreme Personality of Godhead, is like the moon. So we have established this temple, Māyāpur-candrodaya. So this is the idea, that Śrī Caitanya Mahāprabhu is just like moon. Śrī Caitanya Mahāprabhu, He appeared in this land of Māyāpur; therefore He is said here as “the moon.” Therefore we say candra, Māyāpur-candra. Now, as Śrī Māyāpur-candra is rising . . . rising. Rising means He is to distribute the moonshine all over the world. This is the idea, moonshine. Śreyaḥ-kairava candrikā-vitaraṇam. Śreyaḥ-kairava. Caitanya Mahāprabhu personally said. Don’t keep Śrī Caitanya Mahāprabhu compact in your room and take some monetary profit. This is not required. This is not required.
You must allow Śrī Caitanya Mahāprabhu to rise more and more so that this sun, moonshine, may be distributed all over the world. That is wanted. Therefore this temple is situated. Of course, we shall try to construct a very nice temple for Śrī Caitanya Mahāprabhu. This morning we were thinking of this. So from this place, this moon, Śrī Kṛṣṇa Caitanya Mahāprabhu, will distribute. Śreyaḥ-kairava-candrikā-vitaraṇaṁ vidyā-vadhū-jīvanam. The Śrī Caitanya Mahāprabhu’s Hare Kṛṣṇa movement . . . paraṁ vijāyate śrī-kṛṣṇa-saṅkīrtanam. This is spoken by Śrī Caitanya Mahāprabhu Himself. Ceto-darpaṇa-mārjanam bhava-mahā-dāvāgni-nirvāpaṇaṁ śreyaḥ-kairava-candrikā-vitaraṇaṁ vidyā-vadhū-jīvanam (CC Antya 20.12). Vidyā-vadhū-jīvanam. This is real enlightenment. People all over the world, they are in darkness. The moonshine will enlighten them.
