Oh man; I've been reading that sort of stuff too long. That passage you cited makes perfect sense to me:
There are seven ways that wrath, or rebellion against the spiritual order, appear to man: darkness (here, probably an inability to intuitively experience the spiritual), desire (or, a lack of serendipity), ignorance, a fondness for violence, lust (sensuousness), thinking according to the ways of the flesh, and wrathful wisdom (thinking according to rationalization or self-interest?).
The soul climbing towards enlightenment experiences each of these in progression.
It's pretty much standard eastern philosophy mush, the kind that makes for the cheesy science-fiction "fortune cookie" platitutdes that are found abundantly in movies like The Matrix and Star Wars.
Isn't "lust" and "thinking according to the ways of the flesh" the same thing. Ditto for "desire" and "wrathful wisdom". Actually, the whole damn thing sounds like a fortune cookie. Sorry... I was never this jaded about eastern religions until I moved to LaLa Land. After witnessing its nominal practice out here in all its shallow mystical bull-sh*t glory, I just have no patience for it. I would have a heck of a lot more respect for these Buddhist gurus if they did something to improve the lifes of the poor benighted wretches in their own homeland instead of jet-setting around La Jolla to be wined and dined by vapid rich people who want "religion" but are too immoral and self-absorbed to seek anything more than a feel-good spirituality that sounds cool and doesn't frown upon their decadent lifestyle. As it stands, they left the job of taking care of their poor to a Catholic nun from Albania.
