Mantra 11

स यथार्द्रैधाग्नेरभ्याहितस्य पृथग्धूमा विनिश्चरन्त्येवं वा अरेऽस्य महतो भूतस्य निःश्वसितमेतद्यदृग्वेदो यजुर्वेदः सामवेदोऽथर्वाङ्गिरस इतिहासः पुराणं विद्या उपनिषदः श्लोकाः सूत्राण्यनुव्याख्यानानि व्याख्याननीष्टं हुतमाशितं पायितमयं च लोकः परश्च लोकः सर्वाणि च भूतानि ।अस्यैवैतानि सर्वाणि निश्वसितानि ॥बृह. ४,५.११ ॥

In plain words

as from a fire laid with damp fuel separate smokes go out, so from this great being has been breathed out the Ṛgveda, the Yajurveda, the Sāmaveda, the hymns of the Atharvans and Aṅgirases, story and ancient lore, the sciences, the Upaniṣads, the verses, the aphorisms, the explanations and the commentaries; what is sacrificed and offered, what is eaten and drunk, this world and the world beyond and all beings. All these are its breathings out.
