tasmāt–Therefore; vidhāna-uktāḥ–scripturally prescribed; yajña-dāna-tapaḥ-kriyāḥ–duties of sacrifice, charity, and austerity; brahmavādinām–of the followers of the Vedas; satatam pravartante–are always initiated; udāhṛtya–uttering; om iti–the syllable Om, representing

Brahma, the Absolute. [24]

Thus the followers of the Vedas always utter the syllable Om representing Brahma, the Absolute, to initiate their prescribed duties of sacrifice, charity, and austerity.
