Contentment is probably something to which we all aspire, and yet we are not content when we are working too hard, not being paid enough, trying to make ends meet, the kids are playing up, our significant other is on a separate mission, there's crime all around, the Syrians are using weapons of mass destruction on each other, our politicians are corrupt, and, and...
The first question is: what is contentment? It is a state of being happy and satisfied, according to the dictionary. I would suggest adding the words: "...with things exactly as they are."
This seems to be the nub of the issue. It doesn't help to be content only in fair weather, because when the storm clouds gather contentment gets blown away in the gusts. It seems to me that the essence of contentment is to be content, come what may.
And what this takes is a deep and full acceptance of whatever Life delivers, just as it is. The moment we demand that Life should be different from the way that it is, we cannot be content, as we are then subject to what my friend and teacher, Gavin Harrison, refers to as 'the tyranny of the shoulds'.
So the question is: what will it take for you to let go every demand that Life should be different and rather accept each exquisite moment, just the way that it is?
