SB 4.30.5
suparna-skandham arudho
meru-srngam ivambudah
pita-vasa mani-grivah
kurvan vitimira disah
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
The Personality of Godhead, appearing on the shoulder of Garuda, 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-mani. The bodily effulgence of the Lord dissipated all the darkness of the universe.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
As stated in Caitanya-caritamrta (Madhya 22.31):
krsna — surya-sama; maya haya andhakara
yahan krsna, tahan nahi mayara adhikara
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-gita (7.8) the Lord says, prabhasmi sasi-suryayoh: “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-samhita: yasya prabha prabhavato jagad-anda-koti. Being illuminated by the bodily effulgence of the Supreme Personality of Godhead, everything is freed from all darkness.
