The repair of each aspect through the Male and Female comes about through the mystery of Coupling, Pregnancy and Birth. Through coupling, the respective parts of MaH and BaN are channeled until everything is placed in the Female. There in a single whole is found everything that needs to exist in the light in question so that there will be no need to add or subtract. Afterwards this overall whole must be differentiated into its detailed parts and the offspring is not revealed on its own until it is fully established in all its different parts as a complete revelation.
Until that time it is therefore concealed within the light upon which it depends in order to receive its completion from it. This is because the lights of the one (the offspring) can only be completed through the lights of the other (the Female in which it is formed). When it has reached the stage where all its details are visible except that each contains only the minimum possible degree of radiation, the offspring is then revealed on its own, since there is no further differentiation that the light can undergo and it can only gain added power and radiance (the mental powers that enter during the time of suckling). Its being revealed from the higher luminary to the outside is what is called birth.
