1.7.2

atha gāthāṃ gāyati sarasvati predamava subhage vājinīvatī \ yāṃ tvā viśvasya bhūtasya prajāyāmasyāgrataḥ \ yasyāṃ bhūtaṃ samabhavadyasyāṃ viśvamidaṃ jagat \ tāmadya gāthāṃ gāsyāmi yā strīṇāmuttamaṃ yaśa iti \2\

He then sings a song: 'Sarasvatî! Promote this (our undertaking), O gracious one, bountiful one, thou whom we sing first of all that is, in whom what is, has been born, in whom this whole world dwells—that song I will sing to-day which will be the highest glory of women.'
