What was the area that the dead would pass through in egypt

Preparing for the Afterlife - Mr.Donn

To the ancient Egyptians, the Land of Two Fields was a real place. It was a heavenly place. It was the place you went after you died. One of the reasons the god Osiris was so honored in ancient Egypt is because it was Osiris who opened the door to the afterlife for everyone.

Egyptian Afterlife - The Field of Reeds

The ancient Egyptians believed that life on earth was only one part of an eternal journey which ended, not in death, but in everlasting joy. One was born on earth through the benevolence of the gods and the deities known as The Seven Hathors then decreed one's fate after birth; the soul then went on to live as good a life as it could in the body it had been given for a time. When death came, it was only a transition to another realm where, if one were justified by the gods, one would live eternally in a paradise known as The Field of Reeds. The Field of Reeds (sometimes called The Field of Offerings), known to the Egyptians as A'aru, was a mirror image of one's life on earth. The aim of every ancient Egyptian was to make that life worth living eternally and, as far as the records indicate, they did their very best at that.
