यस्यामृचि तामृचं यदार्षेयं तमृषिं यां देवतामभिष्टोष्यन्स्यात्तां देवतामुपधावेत् ॥ ९ ॥

1.3.9 — yasyamrichi tamricham yadarsheyam tamrishim yam devatamabhishtoshyansyattam devatamupadhavet || 9 ||

Let him quickly reflect on the Rik in which that Sâman occurs; on the Rishi (poet) by whom it was seen or composed; on the Devatâ (object) which he is going to praise;

जिस ऋक् में वह साम निहित है, उस ऋक् का स्मरण करे; उसके आर्षेय (द्रष्टा ऋषि) का स्मरण करे; जिस देवता की स्तुति करनी है, उस देवता का अनुध्यान करे।
