When I was a child, and dreamed of being a wizard, this is how I thought I would look. Dude looks awesome….and I don’t care what you say, how you feel and look while practicing your magic is important. I know a lot of you non-GD magicians (and some of you lazier GD mages…=) ) do your work in whatever you happen to be wearing, and that’s fine if it works for you. I personally think the vestments serve an important purpose; they help to create the proper frame of mind for magical work. When I don my robe and sash, I’m not just my mundane self, I’m myself as Magician–the Magician bit is highlighted and brought to the front.
I have heard arguments against robes, implements, titles and so on for some time and to be perfectly honest almost got to a point where lazyness became a virtue (“look mom, no hands”).
One could see a non implement approach as a sign of skill but still, after all is said and done, “like attracts like”.
The same “free” pagans (in my case ) that would call robes and titles silly and superflous would gladly make themselves a talisman.
Robes, as oppose to God forms, are physical, material. Thus if “like attracts like” any operation with an desired outcome of a material nature should be strengthened by wearing, weilding and navigating among material symbols.
Thus reaching the conclusion that Thaumaturgists should really benefit from it (the Goetic circle and triangle are always physical for example).
Next ritual i will don my robe while playing “Putting on the ritz” at full volume.
