Yasya prabhā prabhavato jagad-aṇḍa-koṭi. Jagad-aṇḍa means universe, and koṭi means hundreds and thousands. One hundred times of one hundred thousand; that means innumerable. There are innumerable universes—innumerable suns, innumerable moons, innumerable planets. So this is being possible in the effulgence, brahma-jyoti, of Kṛṣṇa.
Kṛṣṇa's bodily effulgence is called brahma-jyoti. It is stated in the Bhagavad-gītā, brāhmaṇaḥ ahaṁ pratiṣṭhā. The brahma-jyoti . . . those who are jñānīs, those who are trying to approach the Absolute Truth by mental speculation, by dint of our teeny knowledge, they can, utmost, approach to this brahma-jyoti. But that brahma-jyoti is only emanation of the bodily effulgence of Kṛṣṇa. Yasya prabhā prabhavato (Bs. 5.40). Just like the light and the illumination is coming from the light, from that localized bulb, similarly, the brahma-jyoti is coming out.
Just like the sunshine, the best example, the sunshine, illumination of the sunlight, sunshine, is coming from the sun planet. The sun planet is localized. We can see it. And the effulgence, and the bodily effulgence of the sun planet is distributed all over the universe. Similarly, sun planet is one of the material creation of Kṛṣṇa. But as the moon planet reflects the sun planet, similarly the sun planet also reflects brahma-jyoti, and the brahma-jyoti comes out of the bodily effulgence of Kṛṣṇa.
