Kanda 1,Prapataka 2,Anuvaka 13 by Iyer

Yunjathe mana uta yunjathe diyo Vipraah
viprasya brihatho vipaschitha
vi hotra dadhe vaayuna vidheka it
mahhe devasya savituh parishtuthi
suvaag deva duryaam aa vada
devashrutau deveshu aa goshethaam
aa no veero jaayathaam karmanyo
yam sarve anu jeevama
yo bahunaam asath vaashi
idham vishunur vichakrame
tredha ni dhadhe paadam
samoodamasya paamsura
iraavathee dhenumathi hi bhootham
sooyavasini manase yashasye
vyaskambhnaath rodasi vishnur ete
dadhara prithveem abhito mayookhai
praachee pretham adwaram kalpayanthi
oordham yajnam nayathaam
maa jihwarathaam
athra ramethaam varshmaan pridhivya
divo vaa vishno uta vaa
pridhivya maho vaa vishno uta
vaa anthareekshaath hastau prinaswa
bahubhir vasavyaih
aa pra yacha dakshinaath uta savyaath
