I don't understand the part in italics. Is it saying that Jane's puberty was similar to the menarchal ceremony held by Eskimo and South Sea Island tribes?
Jane's ritual imprisonment here, and the subsequent episodes of ostracism at Gateshead, where she is forbidden to eat, play, or socialize with other members of the family, is an adolescent rite of passage that has curious anthropological affinities to the menarchal ceremonies of Eskimo or South Sea Island tribes. The passage into womanhood stresses the lethal and fleshly aspects of adult female sexuality. The "mad cat," the "bad animal" (as John Reed calls Jane),31 who is shut up and punished will reappear later in the novel as the totally animalistic, maddened, and brutalized Bertha Mason; her secret chamber is simply another red-room at the top of another house.
