This is what we found on Wikipedia regarding the Anuv Jain:

A world is a totality of entities. In philosophy, the world is customarily viewed as all of existence or the whole of reality. Some conceptions see the world as unique, while others examine the character of entities that exist in the world or talk of a plurality of worlds, challenging the idea that the world is an all-inclusive whole. The term is also commonly used as a context-dependent expression to denote a specific domain of discourse and everything within it, such as the Earth and all life on it or the whole of human existence.

Theories of modality talk of possible worlds as complete and consistent ways how things could have been. Phenomenology, starting from the horizon of co-given objects present in the periphery of every experience, defines the world as the biggest horizon, or the "horizon of all horizons". In philosophy of mind, the world is contrasted with the mind as that which is represented by the mind.

Theology conceptualises the world in relation to God, for example, as God's creation, as identical to God, or as the two being interdependent. In religions, there is a tendency to downgrade the material or sensory world in favour of a spiritual world to be sought through religious practice. A comprehensive representation of the world and our place in it, as is found in religions, is known as a worldview. Cosmogony is the field that studies the origin or creation of the world, while eschatology refers to the science or doctrine of the last things or of the end of the world.

In various contexts, the term "world" takes a more restricted meaning associated, for example, with the Earth and all life on it, with humanity as a whole, or with an international or intercontinental scope. In this sense, world history refers to the history of humanity as a whole, and world politics is the discipline of political science studying issues that transcend nations and continents. Other examples include terms such as "world religion", "world language", "world government", "world war", "world population", "world economy", or "world championship".
