A?va? (a Sanskrit word for a horse) is one of the significant animals finding references in several Hindu scriptures. The corresponding Avestan term is aspa. The word is cognate to Latin equus, Germanic ehwaz, all from PIE *hek'wos.
The legend states that the first horse emerged from the depth of the ocean during the churning of the oceans. It was a horse with white color and had two wings.
