Bhagavad Gita 10.2 — Source of gods and sages
न मे विदुः सुरगणाः प्रभवं न महर्षयः। अहमादिर्हि देवानां महर्षीणां च सर्वशः ॥
na me viduḥ suragaṇāḥ prabhavaṃ na maharṣayaḥ | ahamādirhi devānāṃ maharṣīṇāṃ ca sarvaśaḥ ||
Meaning
Neither the gods nor the great sages know where I come from. I am the source of all the gods and sages in every way.
