Buddhism is a dharmic, non-theistic religion, which is also a philosophy and a system of psychology. Buddhism is also known as Buddha Dharma or Dhamma, which means the "teachings of the Awakened One" in Sanskrit and Pali, the languages of ancient Buddhist texts. Buddhism was founded around the fifth century BCE by Siddhartha Gautama, hereafter referred to as "the Buddha". (wikipedia)

Numerous distinct groups have developed since the passing of the Buddha, with diverse teachings that vary widely in practice, philosophical emphasis, and culture. However, there are certain doctrines which are common to the majority of schools and traditions in Buddhism, though the Mahayana tends not to regard them as central.
