Who was Buddha? What were his teachings?
Buddha was the founder of Buddhism. His main teaching were, the world is transient (anicca) and constantly changing; it is also soulless ( anatta) as there is nothing permanent or eternal in it. Within this transient world, sorrow (dukkha) is intrinsic to human existence. It is by following the path of moderation between severe penance and self-indulgence that human beings can rise above these worldly troubles.
