kurvan vitimirā diśaḥ
As stated in Caitanya-caritāmṛta (Madhya 22.31):
kṛṣṇa — sūrya-sama; māyā haya andhakāra
yāhāṅ kṛṣṇa, tāhāṅ nāhi māyāra adhikāra
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.
