The OP mentioned about [Sri Madhvacharya's interpretation][1] of Manyu Sukta in the Comment section, and thus I am not mentioning about it again. So I will confine my answer to my observation only. Sri Madhvacharya interpreted the Veda, suiting to his way of worshipping the Almighty God. Another such interpretation is on [Balitha Sukta of Rig Veda][2]. ---- Rig Veda [X.83][3] and [X.84][4] mention about Manyu Sukta. We have to remember that the brAhmanAs and subsequent literature came into existence ***to interpret the Veda and as an extension of the Veda***. The Stories or Myths that were indicated in the [Bṛhaddevatā][5], like fight of Vamadeva with Indra, Indra-Vaikuntha, etc, had been the products of subsequent literature only, which do not find place in Rig Veda. ---- We have to remember that Vishnu was mentioned as an epithet of the Almighty God in Rig Veda, as Indra, Agni, Vayu, etc, were mentioned. We should also remember that the [3 steps of Vishnu][6] mentioned in the Rig Veda does not indicate the Vamana avatara, but indicates the all pervasiveness of the Almighty God. ---- If we understand this background of the Rig Veda, then we can easily understand that Sri Madhwacharya wrongly interpreted the Manyu Sukta. The Manyu Sukta is dedicated to Manyu. Joel P. Brereton and Stephanie W. Jamison write in their translation to X.83, as follows. > This hymn begins with four verses praising Manyu for his might and > victory-bringing qualities and entreating him to use these qualities > against our enemies. The following three verses (5–7) strike a more > personal note, with a 1st-person speaker, apparently deserted by Manyu > for some undetermined reason. The speaker begs Manyu to return to his > side, so that together they can smite the enemy.
