Man/woman
Woman is deeply secure and resilient, but beyond a certain point she breaks, and is as broken as can be. In contrast, the man is much less secure at any stage, though always retains some control. It is like one person who can fall off a boat and swim to safety, and another who cannot swim and will surely drown.
Therefore a man can come to the conclusion "All is false. All I do is selfish," and can still live with the consequences. For he has the leisure of being able to abandon the boat and still swim. But the woman must not consider leaving the safety of her boat. She will not consider "all is false", for what else will be left for her? Thus she is severely limited in the realm of spirit.
