In Egyptian beliefs, the cycle of life, death, and rebirth is signified by the concept of the afterlife, where one's soul transitions into a new existence. The god Osiris plays a crucial role, symbolizing resurrection and eternal life, as he was killed and subsequently revived. Rituals surrounding the afterlife were vital in ancient Egypt; mummification and funerary practices were intended to prepare the deceased for their journey to the underworld. This belief emphasizes the importance of morality, legacy, and the hope for eternal life in Egyptian culture.
