Meditating on the thought for today found in the Magnificat (see a snippit below), I was reminded of the words of Saint Francis as he taught what perfect joy is. You can find "Perfect Joy" at http://www.feastofsaints.com/perfectjoy.htm
Here is the meditation:
"It is necessary that the saints should live among us, that they should be subject, like us, to all the wretchedness of our human condition, and that they should even seem to be overwhelmed by it; for in this way they teach us to be indifferent to all the glory of the world, proving to us in a striking manner that our true good lies elsewhere. The essence of holiness often manifests itself most clearly in the frustration the saint endures, in the pain which is inflicted on him, or which he inflicts on himself, in torture or in martyrdom... Yet our imagination needs these great examples as a measure of the distance there is between holiness and success... (holiness) is indifferent to worldly success and indeed despises it."
