" The theme of submission as an essential attitude toward promotion of the successful initiation rite can be clearly seen in the case of girls or women. Their rite of passage initially emphasizes their essential passivity, and this is reinforced by the physiological limitation on their autonomy imposed by the menstrual cycle. It has been suggested that the menstrual cycle may actually be the major part of initiation from a woman's point of view, since it has the power to awaken the deepest sense of obedience to life's creative power over her. Thus she willingly gives herself to her womanly function, much as a man gives himself to his assigned role in the community life of his group. "
