Spirituality: Enlightenment by Anthony de Mello, S.J.

"Calamities can bring growth and Enlightenment," said the Master.

And he explained it thus:

"Each day a bird would shelter in the withered branches of a tree that stood in the middle of a vast deserted plain. One day a whirlwind uprooted the tree, forcing the poor bird to fly a hundred miles in search of shelter -- till it finally came to a forest of fruit-laden trees."

And he concluded: "If the withered tree had survived, nothing would have induced the bird to give up its security and fly."
