The councillors of Ahura-mazda--called Amesha Spentas, or "Immortal Saints," afterwards corrupted into Amshashpands--wore Vohu-mano (Bahman), Asha-va-hista (Ardibehesht), Khshathra-vairya (Shahravar), Qpenta-Armaiti (Isfand-armat), Haurvatat (Khordad), and Ameretat (Amerdat).

Those of Angro-mainyus were Ako-mano, Indra, Qaurva, Naonhaitya, and two others whose names are interpreted as "Darkness" and "Poison." Vohu-mano (Bahman) means "the Good Mind." Originally a mere attribute of Ahura-mazda, Vohu-mano came to be considered, first as one of the high angels attendant on him, and then formally as one of-his six councillors.

He had a distinct sphere or province assigned to him in Ahura-mazda's kingdom, which was the maintenance of life in animals and of goodness in man.
Asha-vahista (Ardibehesht) means "the Highest Truth"-- "Voritas optima," or rather perhaps "Veritas lucidissima." He was the "Light" of the universe, subtle, all-pervading, omnipresent.

His special business was to maintain the splendor of the various luminaries, and thereby to preserve all those things whose existence and growth depend on light.
Khshathra-vairya (Shahravar), whose name means simply "possessions," "wealth," was regarded as presiding over metals and as the dispenser of riches.
Qoonta-Armaiti (Isfand-armat)--the "white or holy Ar-maiti," represented the Earth.

She had from the first, as we have already seen, a distinct position in the system of the Zoroastrians, where she was at once the Earth goddess and the genius of piety.
Haurvatat (Khordad) means "health"-- "sanitas"-- and was originally one of the great and precious gifts which Ahura-mazda possessed himself and kindly bestowed on his creatures.
