Celestialism, also interchangeably known as astralism or astronomicalism, is the metaphysical belief at the basis of some schools in Astronist philosophy and religion holding that the astronomical world is made up of two fundamental substances, matter and spirit, and is essentially the application of the belief in spiritualism to an astronomical scale. Celestialism forms the foundations for much transtellationist belief, especially regarding the journey of the soul in the afterlife through the astronomical world.
This very broad metaphysical distinction is further developed into many and various forms by the inclusion of details about what spiritual entities exist in the astronomical world and their relationship to The Cosmos itself, such as a soul, the afterlife, spirits of the dead, deities and mediums; as well as details about the nature of the relationship between spirit and matter.
