Haphazard reading, constantly varied and as if lighted upon by chance does not edify but makes the mind unstable; taken into the memory lightly, it goes out from it even more lightly. But you should concentrate on certain authors and let your mind grow accustomed to them.
The light of wisdom is kindled by fervent prayer, just as the light of knowledge is by frequent reading, provided that when you read you use a burning lamp, that is, justice in your deeds and devotion in your sentiments.
Guerric of Igny
