I found this branch of philosophy by doing an online quiz to figure out which philosopher you're like. It was silly but once I started reading about it, I realized that Stoicism is almost the same as my own personal ideas and "spirituality".
I had very strong ideas when I was younger about reaching for a "higher lever of consciousness" and being true to myself and my fate. I lost those ideas as I grew older and ran into issues dealing with my own personal demons which drove me further from who I truly am and who I want to be. Once I hit rock bottom and climbed back out of the rabbit hole, I realized that many of those ideas I had when I was younger were spot on and I looked back to them to start to guide myself in the right direction.
Now, my "spirituality" (for some reason I'm still not sure if I like that word... I haven't found the right word for what these ideas are to me) is something I rely on and want to put into my work because I'd like my work to relate to something bigger then me. I like art that is less specific (like narrative art... I understand it's importance but I have little interest in it), art that connects to something deeper within me and within the world. That is also one reason why I am drawn to abstract art; it has the ability to connect to broader, deeper parts of me and the world. Also because theres many was to see and interpret abstract art; the way I relate to it changes over time and with new experiences.
