Can't be a Spiritual Satanist or a Satanist without Spiritual Satanism. So the only way to have a Satanic mind is to study and Practice Spiritual Satanism.
The #1 best way to practice Spiritual Satanism, is to Take Action with the Wisdom the Gods impart through the High Priests. I once believed the Runes to be the most powerful form of Magick, but I read HP Cobra explain that the Rituals for the Gods are more Powerful. Along with the RTRs to break the Curse of the enemy, so that your mind will not be confused and your path will not be deterred.
It is true that humanity is fated to advance, but we are the ones that must take action on this planet. Take action with Wisdom, and over great lengths of time you will obtain Mastery of the concepts that create the Satanic mind.
