Buddhism is generally considered a religion; However, sometimes the definition of "spiritual philosophy" is made for Buddhism. This is because there is no idea of an absolute creator god in Buddhism. The absence of a creative concept has been one of the distinctive features of Buddhist thought since the time of Buddha. Buddhism's approach is clinical and systematic; In the Four Noble Truths, the Buddha analyzed the problem of suffering, identified its root cause, and wrote the recipe to eliminate suffering. According to the teachings of the Buddha, all sentient beings who follow the eightfold noble path can eliminate ignorance, thus pain, by understanding the concept of "selflessness". Therefore, Buddhism is not based on the concept of a creator god but on concepts of morality, meditation, and wisdom. In this respect, Buddhism contradicts Hindu thought, which defines an ultimate "self."
