57.296

athaitā bhavanti
paryū ṣu pra dhanva vājasātaya
iti pipīlikāmadhyānuṣṭubhaḥ parivatīrantasya rūpam
anto vā anuṣṭupchandasām
ānuṣṭubhametadahaḥ

Then there are these [verses]:
'Flow forth around for the winning of booty,'
which are wasp-waisted Anuṣṭubh verses containing the word pari, a form of the end.
The Anuṣṭubh is the end of the meters.
This day belongs to the Anuṣṭubh.
