ChU 3.12.6
तावान् अस्य महिमा ततो ज्यायांश् च पुरुषः । पादो ऽस्य सर्वा भूतानि त्रिपाद् अस्यामृतं दिवीति
tāvān asya mahimā tato jyāyāṃś ca puruṣaḥ | pādo 'sya sarvā bhūtāni tripād asyāmṛtaṃ divīti
Devanagari rendered by HREEM from the edition's roman (IAST) text; the IAST is the edition's own.
'Such is the greatness of it (of Brahman, under the disguise of Gâyatrî); greater than it is the Person (purusha). His feet are all things. The immortal with three feet is in heaven (i.e. in himself).'
Translated by F. Max Müller
