The Bustan (Persian: بوستان, also transliterated as Būstān, Bustān; "the orchard") is a book of poetry by the Persian poet Saadi, completed in 1257 CE and dedicated to the Salghurid Atabeg Sa'd I or Sa'd II.
The book contains the fruits of Saadi's long experience and his judgements upon life, and is illustrated by a vast collection of anecdotes.
It includes accounts of Saadi's travels and his analysis of human psychology.
The book has ten chapters regarding the issues of ethics and training; namely, justice, mercy, love, humility, contentment, devotions, education, gratitude, repentance, and praying.
[3] In India, Bustan and Gulistan were taught to schoolboys in maktabs, and it had to be learnt by heart.
