Gurdjieff, I came to know him through a discourse from Osho, is a Mystic Master. I've read his book "Meetings with remarkable men" last year. But it is the second in his series "All and Everything" which has 3 books and should be read in the order. Also he suggests to read every book 3 times to grasp the content. He emphasizes the word "read". Because most of the time, we gaze through the book and not involving ourselves with the book.
After reading that book, I've bought his first(Beelzebub's tales to his grandson) and third series (Life is real only then, when I am). But I've to read them yet. Waiting for the right time. I came across "In search of the miraculous" , a book written by his disciple P.D.Ouspensky in which he describes his meetings with Gurdjieff and teachings.
He calls Gurdjieff as G in this book. So far I've read 1/3rd of this book. But it is really astonishing. It has many things in common with eastern thinking. It gives a new idea of many things which we have known or came across already. Also it explores many unknown areas. Especially the "laws of three" and "laws of seven" surprised me.
I would suggest this book to anyone who wants to do a study of science and spirituality together. I will continue reading this..
P.S: Found out a ebook here though I would prefer reading in paper.
