"Mind patterns could be 'woven' like cord patterns, and these mind patterns were what 'move' spells. Different coloured threads indicated different kinds of consciousness, and their physical arrangements had to be projected into equivalent Inner patterns of power" -- From Magical Ritual Methods (affiliate link) by William Gray I pulled this quote while doing a bit of research for Neuro Space/Time Magic. The concept is interesting, using different colored threads to represent specific patterns of thought and being. I was once part of a ritual where we used silver threads to create a tesseract matrix of time. The thread represented the journey to access temporal possibilities, but what I find interesting with this concept isn't even that, but rather how the mind can be organized into different states that can then be evoked using a simple prop such as a colored thread, and a pattern or shape to bring it forth.
This concept can be replicated with other methods as well, such as using an alphabet of desire to embody different states of consciousness and patterns of reality. The key, however, is to recognize how you will actually use a specific state of being to change a pattern of reality you are in. Lets say you are doing a habitual behavior that you want to change. You are aware of it, and you can name it, and provide a symbol/shape to embody it. Now you could take this embodied shape and destroy it, but would that really solve your problem?
An alternate approach would be to devise a symbol and/or shape that represented a desired state of mind/being that you could use to counteract the habitual behavior. Ideally, this symbol/shape could even be the same color of the initial symbol you developed to represent the habitual behavior. Thus when you started to do the habitual behavior, you could visualize the shape and letter of that state, and even vocalize it. Then you could change the shape and letter to the new state of being, even as you also changed the vocalization, imprinting the new behavior on the habit, in order to change it into the new behavior.
All of this I got from a quote by Gray. If you haven't read his books, give them a try. They offer a lot to any occultist lucky enough to find them.
