Discordianism is a "Ha Ha, Only Serious" 'joke', using humor to subversively spread what its members regard as a valid philosophy. To keep said beliefs from becoming dangerous fanaticism, they rely on self-subverting Dada-Zen humor, with varying degrees of success. There is some division as to whether it should be regarded as a parody religion, and if so to what degree.
It has been likened to Zen, based on similarities with absurdist interpretations of the Rinzai school. Discordianism is centered on the idea that chaos is all that there is, and that disorder and order are both illusions that are imposed on chaos. These are referred to, respectively, as the "Eristic" and "Aneristic" illusions. Discordianism recognizes the positive aspects of chaos, discord, and dissent as valid and desirable qualities, in contrast with most religions, which idealize harmony and order.
It is difficult to estimate the number of followers and correctly identify Discordian groups. There is an encouragement to form schisms and cabals. Additionally, few adherents hold Discordianism as their only or primary faith.
