ŚVETĀŚVATARA UPANISHAD · 2.16
एष ह देवः प्रदिशो ऽनु सर्वाः पूर्वो ह जातः स उ गर्भे अन्तः ।
स एव जातः स जनिष्यमानः प्रत्यङ् जनास् तिष्ठति सर्वतोमुखः ॥
eṣa ha devaḥ pradiśo ’nu sarvāḥ pūrvo ha jātaḥ sa u garbhe antaḥ ।
sa eva jātaḥ sa janiṣyamānaḥ pratyaṅ janās tiṣṭhati sarvatomukhaḥ ॥
He indeed is the god who pervades all regions: he is the first-born (as Hiranyagarbha), and he is in the womb. He has been born, and he will be born. He stands behind all persons, looking everywhere.
