Yes, it does affect my art, I produce Electronic Music, play Piano and practice Chi Qong/Kung Fu and since I started with magick, I was a lazy person, not very bright, I mean I am smart being Mexican, but I have seen way smarter people around me, and when some person recommended me Golden Dawn Magick, I started practicing and few weeks after I did the rituals I noticed my imagination was more active, and the "minds eye" was working better, now I have changed to Ogdoadic Magick and find out that for example Invoking Air it helps directly with Music.
The people that recommended me Golden Dawn also speak of doing Chi Qong to energize the body, feel subtle energy, so is like part of my ritual, and Ive been doing it almost daily for 3 years and I love to get better at moving myself in a way is called Martial Arts.
For the Piano I heard from Magick books that some Gods associate to Arts, Science like Hod/Hermes so I try to keep in mind that I play the Piano for them, as a sacrifice, showing that I ve changed and I am a better person, so I can one day dedicate music to the Gods, I produce Electronic Music, but I would love to make Piano song for the Gods.
