It’s an interesting thought. Can’t remember reading anything about G administering seemingly physical blows, but it’s certainly well documented in other traditions ie yogic, zen etc

The blow only seems physical though. Castaneda and these others would have it, that it is really the interaction of their ‘second bodies’; In Gurdjieff’s terminology, the kesdjan body.

The ‘blow’ is administered to the area of the ‘second body’ where the first attention is assembled. ie the attention we have hooked on to our everyday consensus world.

Interesting to compare this notion about the interaction of energy bodies, with some of the more esoteric martial arts. ie Hsing-i, Ba Gua and kuji-kiri
