Acharya Madhvara Mahatreyopanishat Bhashya published in Kannada and Sanskrit in PDF format.

The first of the Upanishads described here is the Aitareyopanishad, which belongs to a section of the Rigveda. This is Acharya's favorite Upanishad, so he wrote an extensive commentary on the subject. This Upanishad is also known as Mahatareyo Upanishad, as written by him in the complete Upanishad portion of the Aranyaka.

This Upanishad, which emphasizes the view that all names are the names of God, is more clearly explained by Madhvacharya, a ethicist. While other commentators give the meaning of mantras, Acharya gives a rare etymological meaning, which gives us a new perspective.

Acharya begins his commentary by saying that the Aitareyopanishath came from Brahmadeva to the line of seers. The followers of the Rigveda took its study as part of their heritage. The most mysterious powers of Narayana Tattva are introduced here.
