Zoroastrianism
Zoroastrianism states that the urvan, the disembodied spirit, lingers on earth for three days before departing downward to the kingdom of the dead that is ruled by Yima. For the three days that it rests on Earth, righteous souls sit at the head of their body, chanting the Ustavaiti Gathas with joy, while a wicked person sits at the feet of the corpse, wails and recites the Yasna. Zoroastrianism states that for the righteous souls, a beautiful maiden, which is the personification of the soul's good thoughts, words and deeds, appears. For a wicked person, a very old, ugly, naked hag appears. After three nights, the soul of the wicked is taken by the demon Vizaresa (Vīzarəša), to Chinvat bridge, and is made to go to darkness (hell).
Yima is believed to have been the first king on earth to rule, as well as the first man to die. Inside of Yima's realm, the spirits live a shadowy existence, and are dependent on their own descendants which are still living on Earth. Their descendants are to satisfy their hunger and clothe them, through rituals done on earth.
Rituals which are done on the first three days are vital and important, as they protect the soul from evil powers and give it strength to reach the underworld. After three days, the soul crosses Chinvat bridge which is the Final Judgment of the soul. Rashnu and Sraosha are present at the final judgment. The list is expanded sometimes, and include Vahman and Ormazd. Rashnu is the yazata who holds the scales of justice. If the good deeds of the person outweigh the bad, the soul is worthy of paradise. If the bad deeds outweigh the good, the bridge narrows down to the width of a blade-edge, and a horrid hag pulls the soul in her arms, and takes it down to hell with her.
Misvan Gatu is the 'place of the mixed ones' where the souls lead a gray existence, lacking both joy and sorrow. A soul goes here if his/her good deeds and bad deeds are equal, and Rashnu's scale is equal.
