Sūta said:: The Saṃhitā texts of Ṛk, Yajus and Sāman are recited by the great sages differently with changes in the settings (arrangements) of Mantra and Brāhmaṇa portions and alterations in the notes, accents and letters. Changes are brought about due to the changes in the (presiding) sages and Mantras and confusion in the view-points. They are similar in certain places and altered utterly in certain places due to difference in the points of view.
