Charioteer of Intellect, Tongue

Charioteer of Intellect and Tongue Zarathustra requests Mazdā the Creator to instruct him “so as to become the charioteer (raiθī) of his intellect and tongue.” Rather than a chariot-builder, here Zarathustra regards himself as the potential chariot driver guiding the process of poetic formulation. The metaphor of poetry is con­tinued in the following strophe when Zarathustra says, “I shall yoke the swiftest horses for you . . .” Further, by the fact that the tradition refers to the Gathic maθras themselves as vačastašti-, we may guess that Zara­thustra also saw himself, or was seen by his followers, as a “fashioner of speech,” since in Avestan taš- was the appropriate verb for chariot-building, as Miθra’s “chariot (was) constructed by (Spənta) Mainiiu (vāša mainiiu.hąm.tāšta, Yt. 10.67). http://www.iranica.com/newsite/index.isc?Article=http://www.iranica.com/newsite/articles/v5f4/v5f4a017.html
