Mr. Gurdjieff disowned this one...
Actually, I didn't read this book. Mr. Gurdjieff advised against doing so and apologized to those who already had. Apparently, his plans changed and his writing skills increased so he decided that it wasn't worth looking at. There's nothing in it that's "bad" or that will send you down the "false path" (or maybe it will, actually), mind you. But it seems that if you're really interested in trying to understand Gurdjieff's ideas or just trying to understand in general then you're just wasting valuable time with this one. Via con Dios.
