“There is a Persian proverb: 'To test that which has been tested is ignorance.' To try to test something without the means of testing is even worse.”

Afghan author, thinker, and teacher, 20th century

Idries Shah, also known as Idris Shah and Indries Shah, was an Afghan author, thinker, and teacher in the Sufi tradition. He wrote in the 20th century and used the pen name Arkon Daraul. He is remembered for work that brought together Sufi teaching, psychology, spirituality, travel writing, and cultural studies. Shah wrote more than three dozen books across those fields, moving between reflective, practical, and exploratory subjects. His work often connects inner life with broader questions of culture and belief, which is why he is read both as a spiritual writer and as an interpreter of ideas and traditions.
