Brahma said. ‘I esteem thee for thy knowledge of divine mysteries, before the whole body of celebrated Munis distinguished for the sanctity of their lives. I know thou hast revealed the divine word, even from its first utterance, in the language of truth. Thou hast called thy present work a poem, wherefore it shall be a poem. There shall be no poets whose works may equal the descriptions of this poem, even, as the three other modes called Asrama are ever unequal in merit to the domestic Asrama. Let Ganesa be thought of, O Muni, for the purpose of writing the poem.’

In plain words: Brahma, the creator god, praises the sage Vyasa in front of many holy sages. He says Vyasa's great poem will have no equal, just as the householder's stage of life is valued above the other stages. He tells Vyasa to call on Ganesha to write it down.
