Mithra (Avestan: Mithra, literally 'covenant' or 'contract') is the great yazata of oaths, alliances, and the light that makes truth visible, celebrated at length in the Mihr Yasht (Yasht 10), one of the longest and most vivid hymns in the Avesta. He rides in a chariot drawn by white horses, possesses 'ten thousand eyes and ten thousand ears,' and surveys all agreements kept or broken across the seven karshvars (regions) of the earth. Mithra is not the sun itself but the all-seeing light that precedes dawn and persists after sunset β the Mihr Yasht describes him as the first yazata to crest Mount Hara before the immortal sun. At the Chinvat Bridge, Mithra serves alongside Rashnu and Sraosha as one of the three judges of the dead, enforcing the covenants each soul made in life.
