पर तत ते अद्य शिपिविष्ट नामार्यः शंसामि वयुनानि विद्वान |
तं तवा गर्णामि तवसम अतव्यान कषयन्तम अस्य रजसः पराके ||

O Lord! I chant your name, to attain Moksha (वयुनानि विद्वान) becoming the best. Myself worship you by chanting you as the one who is eternal (unknown history) and residing at higher altitude of immaterial world(रजसः पराके).
