Other myths reinforce traditions that entrance of souls to the underworld requires a proper observation of ceremony, such as the ancient Greek story of the recently dead Patroclus haunting Achilles until his body could be properly buried for this purpose.
Drugi mitovi ojačavaju tradicije da ulaz duše u podzemni svet zahteva pravilno obavljanje ceremonija, kao što je antička grčka priča o nedavno preminulom Patroklu koji progoni Ahila dok njegovo telo ne može da bude pravilno zakopana radi te svrhe.
