after dedication ritual ,how do I talk to Father Zeus ??Do I need to meditate on his sigil just by looking at it or I need to visualise the sigil in my mind?
Discussion
Either or works. If visualizing is too distracting and not something you're used to then just getting into a meditative state while looking at His sigil works just fine.
Getting better at visualizing is something that you would want to do as well but for this specific part, whichever is more comfortable for you is fine.
Both techniques will work. If you are not able to imagine Satan's Sigil then you don't need to stress about it. Everything will come with time :)
