It's almost like moving meditation; being truly present. I've read other bits by Ouspensky, here and there, and I agree with the nut of what Gurdjieff was trying to elucidate; we are, most of us, sleeping all the time. We think we are conscious, but we aren't. Ouspensky talked about "Remembering the self", and gave an account of how to try to cultivate this technique by being conscious and present while doing other things: walking, talking, &c.
I've been able to get snatches of what I believe they are trying for. When I meditate or do Chi Gong, I become much more receptive to what is "out there".
Hopefully, this can be used as an aid to writing; at the least it's mind-clearing, at best it's inspirational and perhaps will provide some grist for the intellectual mill.
