Mundaka Upanishad 1.9

यः सर्वज्ञः सर्वविद्यस्य ज्ञानमयं तपः | तस्मादेतद्ब्रह्म नाम रूपमन्नं च जायते ॥

yah sarvajnah sarva-vid yasya jnanamayam tapah | tasmad etad brahma nama rupam annam cha jayate ||

From Him who is all-knowing and all-wise, whose austerity consists of knowledge — from Him are produced this Brahman, name, form, and food.

जो सर्वज्ञ और सर्ववित् है, जिसका तप ज्ञानमय है — उसी से यह ब्रह्म (हिरण्यगर्भ), नाम, रूप और अन्न उत्पन्न होते हैं।
