Definition: The term "Eos4a" in context refers to a specific religious practice that has been practiced for over 3,500 years. This practice involves the worshiping of two primary entities: the "Aether," which represents the cosmic light and energy; and the "Cosmos," which is a realm of the universe where everything is believed to exist. The focus is on the unity of these entities in the world's spiritual understanding and the belief that all life exists within this vast, unending cosmos.
