Buddhists in the time of Ancient Japan, although split into many sects, as it is today, believed in generally the same thing that is believed by modern day Buddhists. They believe in the teachings of “The Buddha”, who is seen to be based on an actual historic figure that lived in India around 500BCE. At this time he was “enlightened” where he saw the true nature of the world. After his enlightenment, he taught of the ultimate reality and the true nature of the world. Another main point that Buddhists believed in, was that they were working to eliminate suffering from their life.
When a Buddhist died, they were reincarnated as another being. A continuous cycle of rebirth and death would occur until they attained enlightenment, and ended the cycle, going to a place called “Nirvana”. Nirvana is said to be a place of no suffering, but it is not described in any form as of yet.
