Mbh 12.309.2b

Without doubt, however, O king, this knowledge should be given to one that has conquered one's senses. O Karala, let no fear be thine any longer, since thou hast heard all this regarding high Brahma from me today! I have discoursed to thee duly about high and holy Brahma that is without beginning and middle (and end) and that is capable of dispelling all kinds of grief. Beholding Brahma whose sight is capable of dispelling both birth and death, O king which is full of auspiciousness, which removes all fear, and which benefit, and having acquired this essence of all knowledge, cast off all error and stupefaction today! I had acquired this knowledge from the eternal Hiranyagarbha himself, O king, who communicated it to me for my having carefully gratified that great Being of every superior Soul. Asked by thee today, I have, O monarch, communicated the knowledge of eternal Brahma to thee just as I had myself acquired it from my teacher. Indeed, this high knowledge that is the refuge of all persons conversant with Emancipation has been imparted to thee exactly as I had it from Brahman himself!'"
