Shanti Parva 284.114

You are the fire upon which sacrificial butter is poured. You are he who pours the butter. You are He in honour of whom the butter is poured, you are the butter itself that is poured, and you are the powerful Lord of all. You are those sections of the Brahmanas who are called Trisuparna; you are all the Vedas; and you are the sections called Shatarudriya in the Yajushes.
