The Manual for Little Ones
This book is in Latin.
Fifteen chapters for beginners in the spiritual life: the call of the little ones to Christ, humility and purity, the good use of the imagination, prayer, the guarding of the heart and the reward of eternal life. Latin only: Pohl's critical edition (Freiburg 1918), from a raw OCR of the printed volume; no public-domain English translation has been found.
