ŚVETĀŚVATARA UPANISHAD · 3.4

यो देवानां प्रभवश् चोद्भवश् च विश्वाधिपो रुद्रो महर्षिः ।
हिरण्यगर्भं जनयामास पूर्वं स नो बुद्ध्या शुभया संयुनक्तु ॥

yo devānāṃ prabhavaś codbhavaś ca viśvādhipo rudro maharṣiḥ ।
hiraṇyagarbhaṃ janayāmāsa pūrvaṃ sa no buddhyā śubhayā saṃyunaktu ॥

He, the creator and supporter of the gods, Rudra, the great seer, the lord of all, he who formerly gave birth to Hiranyagarbha, may he endow us with good thoughts.
