My route to this path came mostly through poetry and I continue to learn and identify with the archetypes of Satan, Lucifer, Prometheus etc through writing. There is also an element of personal gnosis gained, learning about the adversary, the light-bearer or the individual whilst I am still writing; meditations, reflections and further reading often inform how I approach the dialogue of a given God, Goddess, Angel, Light-bearer.
Writing is my magick and whilst ritualistic magic is not for me, using the power of the mind certainly is. And no, I don't think that I'm being given something to write, more that all the answers are already latent inside one's own psyche.
One of the core principles that is so well articulated in the Luciferian Overview Sticky by DoP is '...the ability to use mythology and symbolism effectively and learn from it while still being able to recognize it is not actually true...' is indicative of my own standpoint. Prometheus is one of the most important figures for humanity in my own opinion and yet I have no problem accepting he didn't exist. He certainly didn't last 30, 000 years chained to a rock in the Caucasus. Likewise, Satan as light-bearer in the Edenic myth was no more real than Adam and Eve but the symbolism behind both is incredibly important to me and whilst the Semites may have struck a chord with the origin of this myth, it wasn't quite what they (or Milton) thought it was! Apollo and Dionysus also speak to me (a future work no doubt) in the same vein as the above - the intellectual striving coupled with the acknowledgement of the chaotic impulses of the emotional human being are two sides of the same coin.
Neither of these Gods existed as real entities in my own opinion and yet, this is an irrelevance to the learning, advancement, understanding and philosophy that each of them have enabled in me, through my own realisation of what they represent, as archetypes, to me.
