Schools of Buddhism
Since the enlightenment of Siddharta, Buddhism has developed into four main schools. Two centuries after the Buddha died, Buddhism divided into two schools: Theravada and Mahayana.
Theravada Buddhism: Theravada means 'The Teaching of the Elders'. This school focussed on perfecting ones own life according to the original teachings of the Buddha, recorded in the Pali scriptures, in order to reach one's own enlightenment. This traditions remains active in South-East Asia (Thailand, Birma, Sri-Lanka, Laos, Cambodia, Vietnam, etc). There is a strong emphasis on Vipassana meditation in this tradition, aiming for the total eradication of mental impurities and the resultant highest happiness of full liberation.
Mahayana Buddhism: Instead of focussing on the individual this school focuses on helping others to attain enlightenment. Catchwords are compassion, loving kindness, the Boddhisattva, anatta (non-self) and sunyata (emptiness). The Mahayana tradition developed a whole range of sutras in addition to the Buddha's own teachings (e.g. the Lotus, Heart and Diamond Sutra). The Mahayana tradition remains active in the Northern parts of Asia (China, Korea, Japan, Tibet, etc).
The table below sums up the biggest differences between Theravada and Mahayana Buddhism.
