St. John of the Cross wrote over 100 one line advisories that he handed to individuals that were interested in his way of strengthening their faith. Cervantes’ sister was the prioress at a convent across the street from John’s first legal monastery so it is likely that she received or read some of John’s “maxims.”
Cervantes wrote 17 maxims as advice from Don Quixote to Sancho Panza when he was Governor of an “insula.” Insula is usually translated as “island” but I find it curious that the modern translation is an area deep within our brain.
I will use this post to give the first example. (later)
