A Countryman found treasure and gave thanks to the ground. Fortune came asking why he thanked the ground when Fortune would have been otherwise blamed.
Everyone is more or less master of his own fate.
As a Countryman was one day turning up the ground with his plough, he came across a great store of treasure. Transported with joy, he fell upon the earth and thanked her for her kindness and liberality. Fortune appeared, and said to him, “You thank the ground thus warmly, and never think of me. If, instead of finding this treasure, you had lost it, I should have been the first you would have blamed.”
