Sraosha is Ormazd's messenger.

He delivers revelations, shows men the paths of happiness, and brings them the blessings which Ormazd has assigned to their share.

Another of his functions is to protect the true faith.
He is called, in a very special sense, "the friend of Ormazd," and is employed by Ormazd not only to distribute his gifts, but also to conduct to him the souls of the faithful, when this life is over, and they enter on the celestial scene.
Armaiti is at once the genius of the Earth, and the goddess of Piety.
The early Ormazd worshippers were agriculturists, and viewed the cultivation of the soil as a religious duty enjoined upon them by God.
Hence they connected the notion of piety with earth culture; and it was but a step from this to make a single goddess preside over the two.

It is as the angel of Earth that Armaiti has most distinctly a personal character.

She is regarded as wandering from spot to spot, and laboring to convert deserts and wildernesses into fruitful fields and gardens.
She has the agriculturist under her immediate protection, while she endeavors to persuade the shepherd, who persists in the nomadic life, to give up his old habits and commence the cultivation of the soil.
