Accordingly, the whole function of the Nukva is Strengths – renewal of the half of all entities that comes from BaN, i.e. the renewal of their material substance. MaH performs a different and very essential function: the renewal of the material substance of all that exists through interior spirituality. This material substance deriving from BaN is a dark material but it causes one of two things: either joy or sorrow – through repair or destruction. This material substance stands to be repaired with the most exalted of repairs and radiations by MaH, and if it is repaired it generates every kind of joy and love. But if not, God forbid, it causes every kind of sorrow and destruction (see Opening 92).
