Be sure to do the dedication ritual when you can. Don't delay, because the enemy may harass you to stop or turn away from Satan.
As for power meditations, I am also on medication and can only do so much at this current time.I do the aura of protection, aura cleaning, void meditation, affirmations, along with participating in the Spiritual Cleansing rituals.
These, anyone can do without putting themselves at risk if they are dedicated Spiritual Satanists.
I am not a doctor, so I don't know what else to tell you at this time. Maybe someone else, or one of the clergy, can answer, regarding what you can do for meditation.
I am very new to this none the less I'm ready to mmake my dedication I seen on the website that you shouldn't do power meditation On psychotic medication I am currently on Seroquel and triliptol and was wondering if does this have a long term effect on my power meditations or will i EventuallY be able to do them and what kind of effects will this have on my meditation if any at all
