Bhagavatapurana 10.13.56

56. At that moment in his inexplicable curiosity and wonder Brahma had all his eleven senses overpowered and rendered still by their effulgence and he stood in motionless silence like a doll by the side of a village deity.

57. When Brahma, the lord of Saraswati, was unable to perceive what it was and stood perplexed in respect of the incomprehensible ParaBrahman of its own peculiar and unlimited glory shining by itself in perfect bliss, which is known only through Vedic texts that discribe Him (it) in the negative, showing what it is not, the Unborn and Omnipotent Lord, far above Prakriti, soon drew off the curtain of His Maya (from Brahma).
