According to the Sufis, human faculties, although perceptive, are limited: like a radio set, which can receive only certain electromagnetic waves and not other parts of this band. The inability to transcend the barrier of limited senses explains human subjectivity. The Sufis assert that through familiarization with concepts, patterns of thought, and ideas that form part of their contemporary literature, one can learn to penetrate beyond this apparent reality. In this tape set, the listener will experience the unique quality of this material. Shah’s Observations is a fine example of the lucidity and humor prevalent throughout his more than 30 published works. Each observation is a gem of wisdom that can be returned to again and again for more insight. In Letters and Lectures, the listener will become familiar with the Sufi teaching story and with some of the questions and answers exchanged between the Sufi teacher and his students.
