This period of isolation is what we can call the liminal period. Liminality simply means isolation from normality, or normal life.
Within that liminal setting, the initiates in the rite of passage were indoctrinated into the secrets and ways of adult society. In this period, removed from everyday life, the initiates would embrace the messages and symbols provided to them during the ritual.
In theory, they then emerged from the ritual as “new” people—ready to participate in adult society. The liminal moment is the anti-structure, in contrast to the structure of regular life.
In Turner’s theory, both structure and anti-structure play a role in maintaining the stability of society and resolving inevitable tensions.
