The journey to The Duat begins when the Ka (vital spirit) separates from the Ba (personality) upon death, to pass the Hours of the Gates, and become one again, Akhu (immortal). https://youtu.be/SoELyTmZTk0 "This is a fundamental problem with the Egyptology position, and casts their interpretation of the nature of the Duat into doubt. To encounter Osiris, our celestial traveler must pass through Orion, and therefore travel off the ecliptic." http://www.bibliotecapleyades.net/andylloyd/esp_andylloyd_2a.htm
