Buddhism can be explained in different levels. We can see it as a philosophy, as a way of life or as religion. Many years ago when Buddhism prosper, practises or regulations was created for peaceful environment for monks who have to live together. Even though there were no successor appointed in the past by Lord Buddha, there were head monks and abbot of the temple. These kind of formulation made Buddhism a religion. When a group of people live together and practised activities together, that made a formalism and later became a religion. These formalism was made with the intention to make people able to live and avoid Chaotic environment, be able to focus on the teachings about way of life and philosophy.
