If you read P. D. Ouspensky and G. I, Gurdjieff you’ll find that a chunk of the Fourth Way practices entail visualization techniques. Taken superficially, these practices resemble the sort of things going on around the Golden Dawn. However, once we pass beyond a cursory examination of them, they appear quite different. The Golden Dawn seems to have treated the visualizations as a vehicle while for the Fourth Way system it served a kind of mental calisthenics.
The differences can be seen clearly enough in the sorts of visualizations. While the Golden Dawn sorts of practices emphasized symbolic (i.e., water as a symbol of emotion and nourishment) elements, the Fourth Way emphasized abstract and geometric elements for theselves. Obviously, these two branches aren’t entirely disparate. The tree of life as the Golden Dawn portrayed it was pretty darn abstract and geometrical, though if you read Dion Fortune’s pathworkings for it, you’ll realize that the primary means of accessing those forces were through symbolic meditations.
