Although enormously attractive as sheer entertainment, Dervish tales were never presented merely on the level of a fable, legend, or folklore. They stand comparison in wit, construction, and piquancy with the finest stories of any culture, yet their true function as Sufi teaching stories is so little-known in the modern world, that no technical or popular terms exist to describe them. The material in Tales of the Dervishes is the result of a thousand years of development, during which Dervish masters used these and other teaching stories to instruct their disciples. The tales are held to convey powers of increasing perception unknown to the ordinary man.

In Idries Shah's Wisdom of the Idiots, the "idiots" are Sufis, called this because their wisdom penetrates to a depth which renders it inaccessible to the merely intelligent or academically knowledgeable. The stories of the Sufis are tools prepared for a specific purpose. On this level the movements of the characters in a story portray psychological processes, and the story becomes a working blueprint of those processes.

When it first appeared in 1964, The Sufis was welcomed as the decisive work on the subject of Sufi thought. Rich in scope, author Idries Shah explained clearly the traditions and philosophy of the Sufis to a Western audience for the first time. In the five decades since its release, the book has been translated into more than two dozen languages, and has found a wide readership in both East and West. Containing detailed information on the major Sufi thinkers, and literary characters, such as Nasrudin, it is regarded as a key work on both Sufism and Eastern Philosophy.

The Way of the Sufi presents an unparalleled cross-section of material from Sufi schools, Sufi teachings, and classical writings as a basic course of Sufi study. The author begins with the outward aspects of the teaching most likely to puzzle the student coming fresh to the subject. He considers various attitudes to Sufi ideas and evidence of their absorption into medieval Christianity, Hinduism, Jewish mysticism, and modern philosophical teachings.

Condensed from more than three million words, these conversations involve housewives and cabinet ministers, professors and assembly-line workers, on the subject of how traditional psychology can illuminate current human, social, and spiritual problems. More than 100 tales and extracts from Sufi lore, ranging from the eighth century (Hasan of Basra) to the modern Afghan poet Khalilullah Khalili, are woven into Shah’s narratives of how and why the Sufis learn what they learn and how spiritual understanding develops and deteriorates in all societies.
