Thus the actual repair in MaH and BaN brought about through man’s deeds elicits a corresponding radiation of the lights of the other branches, and accordingly when those lights shine it will be through merit, since their radiation was elicited through man’s merit during his repair of MaH and BaN. Thus the time of man’s service is only during the rule of MaH and BaN, but the effects of this service reach the very summit of all levels until the entire repair of MaH and BaN will be complete. Thus it is man’s merit that calls forth each of these levels – the Ears, Nose and Mouth – to shine their lights in turn, each in its proper time (in its respective millennium).
