In ancient Egyptian mythology the fields of Aaru (; Egyptian: iArw meaning "reeds"; altn. Yaaru, Iaru, Aalu), known also as Sekhet-Aaru or the Egyptian reed fields, are the heavenly paradise, where Osiris ruled after he became part of the Egyptian pantheon and displaced Anubis in the Ogdoad tradition. It has been described as the ka (a part of the soul) of the Nile Delta.
