According to Buddhist philosophy, what is the nature of the world?

Transient and constantly changing

In line with Buddhist philosophy, the world is characterized by impermanence (anicca) and continual transformation. Additionally, it is deemed devoid of a permanent, unchanging soul (anatta). Embedded within this ever-changing realm is the inherent presence of suffering (dukkha) within human existence. The teachings advocate finding a balanced path between extreme austerity and indulgence, enabling individuals to transcend these worldly afflictions. In the earliest iterations of Buddhism, the existence of deities held little significance.
