2.6.9

ākūtīm devīm manasā pra-padye
yajñasya mātaram su-havā me astu /
yasyās te ekam akṣaram param
sahasrās ayutam ca śākhās
tasyai vāce ni-have juhomi
ā mā varas gacchatu śrīṣ yaśas ca // svāhā //

With my mind I take refuge in the goddess Intention,
the mother of the sacrifice; may she be easy of invocation for me.
You whose one supreme syllable is
thousands and ten thousands of branches—
to that Speech, at this invocation, I offer.
May a boon come to me, prosperity and glory! Svāhā!
