the role of the Saoshyant, or Astvat-ereta, as a future saviour of the world is briefly described in Yasht 19.88-96, where it is stated that he will achieve the frasho.kereti, that he will make the world perfect and immortal, and evil and Druj (leugen/valsheid/alles wat slecht is) will disappear. He is identified as the son of Vîspa.taurwairî and it is stated that he will come forth from Lake Kansaoya/Kansava and will carry the same weapon Verethragna that a number of Iranian epic heroes and kings have used in the past against various demonic foes. Haurvatat, Ameretat and other similar entities will be his companions and together, they will vanquish the evil creations of Angra Mainyu (duivel).
De Yashts zijn geschreven tussen 800 voor Christus tot ongeveer 200 jaar erna.
Dit is wat Qurani bedoelt eigenlijk, alleen hij heeft t niet verder uitgelegd.
