divyaṁ sahasrābdam amogha-darśano jitānilātmā vijitobhayendriyaḥ atapyata smākhila-loka-tāpanaṁ tapas tapīyāṁs tapatāṁ samāhitaḥ
Translation
Lord Brahmā underwent penances for one thousand years by the calculations of the demigods. He heard this transcendental vibration from the sky, and he accepted it as divine. Thus he controlled his mind and senses, and the penances he executed were a great lesson for the living entities. Thus he is known as the greatest of all ascetics.
