The Bustan of Sadi by Sa'di Shirazi

This is a prose translation of the Bustan of Sadi, originally published as part of the Wisdom of the East series in the early 20th century, and long out of print. This little book is full of practical spiritual wisdom. Sadi doesn't lean on allegory as much as other Sufi writers of the period; most of the stories in this collection have a pretty obvious moral lesson.
