How can someone be given so much and -- rather than being grateful for the abundance of these gifts -- be so negative over a single element in the midst of them? Closer examination of such a situation, and the inconsolable level of self that gives rise to it, may show us that we have more in common with this discontented character than not.
It's impossible for us to identify with the pleasure of wanting something without encountering the pain of not wanting whatever will come to stand between that desire and its fulfillment. In other words, on the flip side of that invigorating feeling called "Yes, I want (this)" is that debilitating state called, "No! I don't want (that)."
Personal experience validates this finding. No matter what we give to desire, it's never enough. One way or another, by its very nature, desire always wants more... which leads us to this astonishing revelation. Please take your time to ponder its meaning until you can see the many self-liberating truths hidden within it.
Our inevitable sense of dissatisfaction with life is inseparable from whatever desire sends us out to claim in the name of its imagined contentment to come.
The nature of desire can never know lasting contentment because it is literally set against itself; it is a "house divided" in the truest sense of the words, and it only stands for as long as it can keep us shoring up its constantly collapsing sides.
Learning to welcome and then act from this new self-knowledge is the same as embracing a new order of consciousness that can't be tricked into acting against itself.
