And the first text on which Sayanacharya wrote his commentary was the Taittiriya Samhita of the Krshna Yajurveda. He himself was a Taittiriya Shakhadhyayi. Therefore, his choice of text seems but natural. Another reason for beginning the commentary literature with the Yajurveda is that, in the performance of Yajnas, of the four rtvijs involved, the adhvaryu is given prime importance for, he guides the yajamana in the procedures of the yajna. And Yajurveda is the text designated for the guidance of the adhvaryu. Since the adhvaryu fulfils his role with the help of the Yajurvedic mantras, in lieu of its utility, it is seen as an appropriate decision to begin authorship of the commentary literature with the Yajurveda.
