The Little Alphabet of the Monk in the School of God
This book is in Latin.
A short dialogue between disciple and master: the rules of the spiritual life set out in alphabetical order, love of obscurity, kindness, guarding the heart, solitude, poverty, and the blessing at the end. Latin only: Pohl's critical edition (Freiburg 1904), from a raw OCR of the printed volume; no public-domain English translation has been found.
