POETRY!
The poetry of Nasir Khusraw is replete with advice and wisdom. Being the representative of the Fatimid Imams in Khorasan, Nasir guided his followers through his poetry. His Persian poetry is enjoyed by the average Persian speaker of today and is taught in grade school. Some of the fables mentioned in his poems were eventually to find their way to the West. Among them is the story of The Gourd and the Palm-tree:
Have you heard? A squash vine grew beneath a towering tree.
In only twenty days it grew and spread and put forth fruit.
Of the tree it asked: "How old are you? How many years?"
Replied the tree: "Two hundred it would be, and surely more."
The squash laughed and said: "Look, in twenty days, I've done
More than you; tell me, why are you so slow?"
The tree responded: "O little Squash, today is not the day
of
reckoning between the two of us.
"Tomorrow, when winds of autumn howl down on you and me,
then shall it be known for sure which one of us is the most resilient!"
نشنیده‌ای که زیر چناری کدوبُنی --- بررُست و بردوید بر او بر، به روز بیست؟
پرسید از آن چنار که: تو چندساله‌ای؟ --- گفتا: دویست باشد و اکنون زیادتی‌ست
خندید از او کدو که من از تو به بیست روز --- برتر شدم، بگو تو که این کاهلی ز چیست
او را چنار گفت که امروز ای کدو --- با تو مرا هنوز نه هنگام داوری‌ست
فردا که بر من و تو وزد بادِ مهرگان --- آنگه شود پدید که از ما دو، مرد کیست
WORKS:
Safarnama (Persian: سفرنامه)
Safarnama (The Book of Travels) is his most famous work. He visited dozens of cities in about seven years (March 6, 1046 - October 23, 1052) and wrote comprehensively about them, including details about colleges, caravanserais, mosques, scientists, kings, the public, the population, the area of the cities, and, of course, his interesting memories. After 1000 years, his Safarnama is still readable for Persian-speaking people.
Diwan (Persian: دیوان)
Among his other works, most of the lyrical poems in his Diwan were composed in his retirement, and their chief topics are an enthusiastic praise of Ali, his descendants, and al-Mustansir in particular, along with passionate outcries against Khorasan and its rulers, who had driven him from his home. It also explores his immense satisfaction with the quiet solitude of Yumgan, and his utter despondency again in seeing himself despised by his former associates and excluded from participation in the glorious contest of life. Scattered through all these alternating outbursts of hope and despair, there are lessons of morality, and solemn warnings against the tricks and perfidy of the world, the vanity of all earthly splendour and greatness, the folly and injustice of men, and the hypocrisy, frivolity and viciousness of fashionable society and princely courts in particular.
Gushayish va Rahayish (Persian: گشایش و رهایش)
Another work of Nasir Khusraw is the Persian philosophical work "Gushayis va Rahayish" which has been translated into English by F.M. Hunzai under the title: "Knowledge and Liberation". The work discusses creation, questions related to the soul, epistemology, creation, and Ismaili Islamic doctorines. From a linguistic point of view, the work is an example of early philosophical writing in new Persian.
Wajh-i din (Persian: وجه دین)
Nasir Khusraw, explains the spiritual interpretation of the tradition of a six day creation of the physical universe. He writes about how the story of creation is a symbolic explanation of what happened when God created the universe. Interpreting it literally is something human beings do based on the limits of their intellects. In the scriptures, when it says that God began the work of creating the world on Sunday, completed it on Friday, and then rested on Saturday, it is not a literal account, rather a symbolic one.
When the Prophets shared the story of a six-day creation of the physical universe, it was meant for the people to understand that God was saying that six prophets would come into this world and command people to work. When the seventh day came, God would not command in this manner, but would rather reward them for their hard work.
Book on Mathematics (Persian: غرایب الحساب و عجایب الحساب)
Nasir Khusraw wrote a book on mathematics which has now been lost. He states in his other work that he could: not find one single scholar throughout all of Khorasan and eastern lands like myself [who] could grapple with the solutions to these problems. But he felt it his responsibility to take the task for readers he would never see, 'those yet to come, in a time yet to come'
Jamiʿ al hikmatayn (Persian: جامع الحکمتین)
