Srimad-Bhagavatam: Canto 4 - Chapter 1 - Verse 5
सुपर्णस्कन्धमारूढो मेरुशृङ्गमिवाम्बुद: ।पीतवासा मणिग्रीव: कुर्वन्वितिमिरा दिश: ॥ ५ ॥
suparṇa-skandham ārūḍhomeru-śṛṅgam ivāmbudaḥpīta-vāsā maṇi-grīvaḥkurvan vitimirā diśaḥ
The Personality of Godhead, appearing on the shoulder of Garuḍa, seemed like a cloud resting on the summit of the mountain known as Meru. The transcendental body of the Personality of Godhead was covered by attractive yellow garments, and His neck was decorated with the jewel known as Kaustubha-maṇi. The bodily effulgence of the Lord dissipated all the darkness of the universe.
As stated in Caitanya-caritāmṛta (Madhya 22.31): The Lord is just like the effulgent sun. Consequently, whenever the Supreme Personality of Godhead is present, there cannot be darkness or ignorance. Actually this dark universe is illuminated by the sun, but the sun and moon simply reflect the bodily effulgence of the Supreme Lord. In Bhagavad-gītā (7.8) the Lord says, prabhāsmi śaśi-sūryayoḥ: “I am the illuminating energy of both the sun and the moon.” The conclusion is that the origin of all life is the bodily effulgence of the Supreme Personality of Godhead. This is also confirmed in Brahma-saṁhitā: yasya prabhā prabhavato jagad-aṇḍa-koṭi. Being illuminated by the bodily effulgence of the Supreme Personality of Godhead, everything is freed from all darkness.
