9.9.6

pā́kaḥ pr̥chāmi mánasā́ 'vijānan devā́nām enā́ níhitā padā́ni |
vatsé baṣkáyé 'dhi saptá tántūn ví tatnire kaváya ótavā́ u ||6||

Simple, not discerning (vi-jñā) with the mind, I ask about the thus set-down tracks of the gods; over the yearling (? baṣkáya) calf have the poets stretched out seven lines (tántu) for weaving.
