कोऽहं कथमिदं जातं को वै कर्ताऽस्य विद्यते ।उपादानं किमस्तीह विचारः सोऽयमीदृशः ॥ १२ ॥
In plain words
Who am I? How did all this come to be? Who is its maker — is there one to be found at all? And what is it made out of? Inquiry, vicāra, is exactly this and nothing else.
Close to the Sanskrit
Who am I? How has this come to be? Who indeed is found as the maker of this? What material cause exists here? — that inquiry is this, of such a kind.
