Separation Bridge

Zoroastrians’ Universe lasts for 12000 years; there are four phases, each for 3000 years. At the first one, good and bad are separated. In the second phase, the hostile forces succeed. The good forces are back in the third one. At the last phase several saviours come. The last one is Saoshyant. When he arrives there is resurrection, walking over the Separation Bridge, Chinvat (Sarat Bridge in Quran) and finally all the hostile spirits will be defeated. Quoted from Iranian Months
