ritual in Raëlism is the "transmission of the cellular plan", in which a Raëlian Guide placed their hands upon another individual's head, through which the Guide is believed to receive the individual's cellular code and then telepathically transmit it to the Elohim. Doing so denotes the initiate's formal recognition of the Elohim as the creators of humanity. This is used as part of the "baptism", or initiation ceremony for new members joining the Movement. Those in the Movement who hold the rank of bishop and priest are permitted to conduct these initiation ceremonies. In some instances, when the necessary individuals are present, Raël touches the head of a Raëlian bishop, who in turn touches that of a Raëlian priest, who touches the head of the initiate to ensure the "transmission". These "transmissions" are permitted to take place on one of four days in the year that play prominent role in the Raëlian calendar. The first examples took place in April 1976, when Raël carried out the "transmission" ceremonies of forty initiates on the Roc Plat. The Raëlian calendar begins with the nuclear bombing of Hiroshima on August 6th 1945. Each year after this date is referred to as "AH" or "après Hiroshima" ("after Hiroshima"). The Raëlians celebrate four religious festivals each year, two of which mark Raël's claimed encounters with the Elohim. These are the first Sunday in April, which is the date on which Raëlians believe the Elohim created the first humans; August 6th, which marks the day of the nuclear bombing of Hiroshima in 1945; October 7th, which is the day in which Raël claims that he encountered the Elohim for the second time, in 1974; and December 13th, which is the day that Raël allegedly first encountered the Elohim in 1973. Sensual meditation A major practice in Raëlism is "sensual meditation", something that Raël outlined in his 1980 book La méditation sensuelle. Raëlians are encouraged to take part in this guided meditation or visualisation on a daily basis, with the intent of transmitting love and telepathic links to the Elohim and achieving harmony with infinity. In this, practitioners are often assisted in this meditation through listening to an instruction tape. Sensual meditation sessions also take place communally at the group's monthly meetings, during which the assembled adherents sit or lie on the floor in a dimly lit room. They are then guided through it by a Raëlian
