spiritual diseases - ever wondered

I was searching google the other day too find something about spiritual diseases. I found this site:

http://www.onlineislamicstore.com/b8118.html

Which gives the following as such diseases.

" Diseases examined include miserliness, envy, hatred, treachery, rancor, malice, ostentation, arrogance, covetousness, lust, and other afflictions that assail people and often control them. The causes and practical cures of these diseases are discussed, offering a penetrating glimpse into how Islam deals with spiritual and psychological problems and demonstrating how all people can benefit from these teachings."

So there you have it, a solution for all those problems.

I wonder where we could find all those characteristics manifested.
