This is why you can't pass the Devil on the way to Tiphareth from Hod. The mind and body are "in chains" to the senses. The intellect alone can't gain entrance to Tiphareth. The Devil is an imaginary phantasm generated by the mind that is incapable of handling the truth of Tiphareth.
But you can get a glimpse of Tiphareth through the Devil, and he is the instrument by which you know what you're looking for in the first place (you know, sex, etc.)
