Another way japan kept structure in society was by using the religion, zen. Zen is a religion that emphasis on effort and discipline which was perfect for samurais, this is also why most samurais followed the teachings of zen. According to the religious teachings of Zen to achieve enlightenment one must give up everyday logical thinking. To jolt ones mind masters would come up with question which are also known as koans. One of the most popular koan is, " What is the sound of one hand clapping?" This is important in society because the religious teachings of zen is what teaches a samurai to learns discipline, focus their minds, and over come the fear of death. Which is basically all the features a samurai needs. Society would be different without the religion of zen because samurais wouldn't be as brave of a warrior as they are now.
