But further than this, my son, inquire not. Knowledge is very well in its place, but it is like flowers without fruit. We cannot feed on knowledge, we cannot thrive on knowledge. Just as the leaves of the grove are very beautiful but would make a bad meal, so we shall ever be hungry and never be satisfied if we think to take knowledge for our food. Knowledge is no food.
Religion is our only food.
Here then is another mortification. Mortify your desire of knowledge. Do not go into excess in seeking after truths which are not religious. Again, mortify your reason. In order to try you, God puts before you things which are difficult to believe.
