In the Saiyasart existential information is information that is natural in its origin or through its existence.

Natural is what is found in this sphere of existence (earth) as characteristic components, and has been defined as basic elements in older descriptions. These are e.g. the air, the earth, the fire and the water. The interaction of these conditions with the properties of the existing basic elements results in additional events and thus also additional existential information (e.g.: a volcanic eruption, a drought or a flood).
