The Arctic Home in the Vedas c13.s5.3

c13.s5.3

Indra is called sapta-rashmi in II, 12, 12, and his chariot is also said to be seven-rayed in VI, 44, 24. But in V, 33, 8, ten white horses are said to bear him; while in VIII, 24, 23, Indra is said to be "the tenth new" (dashamam navam). In the Taittirîya Âraṇyaka III, 11, 1, Indra's self is said to be going about ten-fold (Indrasya âtmânam dashadhâ charantam); and corresponding to it, it may be here noticed, we have in the Bahrâm Yasht, in the Avesta, ten incarnations of Verethraghna (Sans. Vṛitrahan) specifically mentioned. Amongst the proteges of Indra we again have one called Dasha-dyu, or one shining ten-fold (I, 33, 14; VI, 26, 4); while Dashoṇi, a being with ten arms or helpers, and Dasha-mâya, or a ten-wiled person, are mentioned amongst those whom Indra forced to submit to Dyotana in VI, 20, 8. Dashonya and Dasha-shipra are also mentioned to have been by the side of Indra when he drank Soma with Syûmarashmi in VIII, 52, 2.
