The Infinite within the Finite.
To be human is to live with paradox.
There are always tensions between the 'impossible' things our souls yearn for and the 'possible' things the world requires us to accept.
In each of our hearts, we negotiate our own solutions as to how we reconcile the irreconcilable-- how we find a way to live out our inspirations, when we are bound by space and time and constrained by circumstances beyond our control.
Holding a positive animating vision in our consciousness, even perhaps of something not yet created, may be one approach to cultivating an ability to bear what the world asks us to bear. A way to understand our experience as something, if not worthwhile unto itself, then at least as a stepping stone on a path toward something worthwhile.
In short, the trick is to somehow 'fit' the infinite yearnings of the human heart, into the finite life which this world has granted us. The challenge of human life is making peace with this impossible task of placing a box around the infinite...
...kind of like a Roomful of Sky.
