The syllable OM is the root from which the Vedas have originated. He has no fear about next life in all the three worlds, who has uttered for him the syllables 'OM, Namas, Svaha, Svadha, and Vashat, and who has according to his means, celebrated sacrifices and other rites. The Vedas and sages crowned with ascetic success, and the foremost of Rishis declare thus.
ओमिति ब्रह्मणो योनिनमः स्वाहा स्वधा वषट्। यस्यैतानि प्रयुज्यन्ते यथाशक्ति कृतान्यपि॥ न तस्य त्रिषु लोकेषु परलोकभयं विदुः। इति वेदा वदन्तीह सिद्धाश्च परमर्षयः॥
