- Sarosh-no-Kardo or Sarosh-nu-Patru is an after death ritual which is performed on the first, second and third days following death, at the beginning of the Aiwisruthrem gāh, after sun-set. It could be performed either at the Doongerwadi, Agyari/Atash Behram or in any other ritually clean place.
- This ritual cannot be performed at the Bangli in the presence of the dead body, when the body is lying in the Bangli. Hence, if Paydast is on the second day, the Sarosh-nu-Patru will not be performed on the first day. In cases when the body is not in the Bangli and yet not disposed, for instance, if it is in the morgue or has yet not arrived from abroad, then the Sarosh-nu-Patru can be performed.
- For this ritual, two priests perform a specialised Āfrinagān ritual in honour of Sarosh Yazad. They sit on the mat face to face on either side of the Afringan (Pātra or Pātru for holding the fire, hence the name of the ritual) and first recite the Sarosh Baj, then the Aiwisruthrem Gah followed by Sarosh Yasht Vadi, its Nirang and the Doa Nam Setayashne.
- The Zoti, that is, the senior priest, has a metallic tray (khumcho) before him, which contains a metallic container (karasyo) of clean water and a few flowers, eight of which are arranged in a particular order. The other priest sits on the opposite side. The Zoti begins the Afringan with the recitation of the Dibache (lit. introduction), in the Pazand language, wherein he invokes Sarosh Yazad, the name of the deceased is mentioned over here. After the Dibache is finished, both priests recite the Afringan Kardeh aloud in which the seventh Kardeh (section) of Srosh Yasht Vadi is prayed. The ritual ends with both priests reciting the Pazand prayer Patet ravan-ni.
