Near the beginning of Vana Parva, ch. 3 page 12 of the PDF of the Ganguli version is this:
"Thou art called Indra, thou art Vishnu, thou art Brahma, thou art Prajapati. Thou art fire and thou art the subtle mind. And thou art lord and the eternal Brahma."
There are no diacriticals in this PDF, so are both Brahmā or is last one the principle Brahma?
