Second Noble Truth

2.  Noble Truth of the Cause of Suffering.
Not being able to be content with what we have or who we are, our mind is filled with a greed or desire and suffering automatically follows.  
Contentment is one of my six major values.  That doesn't mean that I am always content.  But I have reached an understanding that contentment is a highly desirable state and I make frequent attempts to dwell there.  "Wanting more" is an affliction of our culture which is of great positive value as well as causing suffering.  Otherwise, many desirable accomplishments would never come to fruition.  Still, in the search for enlightenment or bliss or whatever you may call it, contentment is part of reaching for  and attaining that state.
