Bhagavad Gita Chapter 11.31
ākhyāhi me ko bhavān ugra-rūpo
namo ’stu te deva-vara prasīda
vijñātum icchāmi bhavantam ādyaḿ
na hi prajānāmi tava pravṛttim
O Lord of lords, so fierce of form, please tell me who You are. I offer my obeisances unto You; please be gracious to me. You are the primal Lord. I want to know about You, for I do not know what Your mission is.
