Arbaeen, a parade and religious ritual, is one of the modern examples of rituals that are created by the general public in a totally customary environment and include a variety of religious events. 

This religious ritual is entirely autonomous and was not created by any government entity, organization, or human administration. Ironically, during the Arbaeen days, some behavior patterns in the Arbaeen procession led to the development of a distinctive social system.

The fascinating details of this spectacular ritual are covered in the book "Arbaeen, a Different World." Mohsen Araki, Hasan Rahim Pour, Asghar Taher Zadeh, Seyed Mahdi Mirbagheri, and Alireza Panahian are only a few of the specialists who have contributed to this book by way of their remarks and documents from special meetings. 

Masoud Moeinipour put together the book, which was then released by Soore Mehr Publications.
