As you may have noticed at some point in your life, the material aspect* of the universe - which is not too bad per se - can distract from matters intellectual and spiritual. For man, the most distractive kind of thing in the universe is the female body**. Leaving aside her face (as it's mainly spiritual) and breasts (I'm not sure about them - I need to take a much closer look; philosophically, I mean), the most absorbing part of the woman's body is her pussy. Thus, the pussy is the climax of what the material universe can offer a man and at the same time - but not necessarily - the deepest trap in town into which he can fall, or whatever you want to call it.
( - which is kind of obvious to any philosopher after - or even during; if he's a quick thinker - puberty, but I'm sure it's somehow useful to have it expressed as a properly structured, even if slightly too stimulating, philosophical argument).
*I wrote 'material part', but I somehow feel (call me a Feelist, if you like) that 'aspect' is a better word here **gays aside
