The initiate is then secluded in a room in the terreiro called the "roncô", during which time they are termed an "îao". In the roncô, they sleep on a straw mat, eating only bland food; often they will not be permitted to speak. During this period they are taught the various details of their associated orixá, such as its likes and dislikes and the appropriate drum rhythms and dances that invoke that deity. The time spent in isolation varies, although three weeks is typical. They will be bathed in water mixed with herbs, especially their head, which will then be shaved.
