Refreshing and different from the well-known theoretical representations of Gurdjieff's teachings of the Fourth Way, this masterpiece of introspective experience provides exceptionally concrete, authentic insights into the practical aspects of the work along the path of self-knowledge. Jeanne de Salzmann (1889–1990), perhaps the closest student of the great teacher, studied his ideas directly by his side for three decades. When she passed away at the age of 101, just as he had instructed her shortly before his death, she reflected on more than seventy years of practice of what is called "the spiritual work" or "the Work." This impressive book, compiled from her personal notes, captures the inner experiences of implementing Gurdjieff's ideas and practicing his exercises, and analyzes them meticulously.
