Bhagavad Gita · 10.2

न मे विदुः सुरगणाः प्रभवं न महर्षयः।अहमादिर्हि देवानां महर्षीणां च सर्वशः॥

na me viduḥ sura-gaṇāḥ prabhavaṁ na maharṣhayaḥ aham ādir hi devānāṁ maharṣhīṇāṁ cha sarvaśhaḥ

Neither the hosts of gods nor the great sages know my origin, for I am the source of all the gods and great sages in every way.
