Astronism is a naturalistic and cosmocentric religion founded by the philosopher Cometan which officially designated Astronism an 'organised philosophy', which is a term coined by Cometan himself. Astronism is a system of ideas and beliefs which belongs to a wider set of religions called the Astronic tradition of religion whose history can be traced back to the astronomical religions practiced during the Upper Palaeolithic period of the Stone Age. These were some of humanity's first religious beliefs and ideas which makes the Astronic tradition older than any other religious tradition like the Dharmic, Abrahamic and Taoic traditions.
Astronist eschatology teaches that when a person dies, they experience what is known as cosmosis. This process is largely taught and interpreted as a natural process, but depending upon a person's predetermined beliefs, they may choose to incorporate a spiritual element into what they believes happens during cosmosis. Otherwise, cosmosis is a naturally occurring process to all people when they die and essentially involves a person's physical reunion with The Cosmos, after which they cease to exist.
Further to this, an Astronist sees their central religious and philosophical life goal to become one with The Cosmos whilst they are still alive; essentially, achieve this cosmosis, or cosmic union before they die. This is known as astrosis and can be achieved only through consistent contemplation and by following and executing a set of chosen practices as part of an astrosis methodology.
