From the Inside Flap
Of all his books, the Bostan (The Orchard) and the Gulistan (The Rose Garden) are his best known and most admired.
Saadi's Bostan (The Orchard) is one of the greatest of all Sufi Classics. Together with his Gulistan, these two books are regarded as supreme accomplishments of both literature and Sufi thought. They contain a richness of material and beauty of poetry which are almost unparalleled.
The Bostan is a mine of proverbs, quotations and practical wisdom. But like the Gulistan (The Rose Garden) it contains far more than moralistic aphorisms and teaching stories. The Bostan is recognised by eminent Sufis as concealing the whole range of the deepest Sufi knowledge which can be committed to writing.
