Satan is not a supernatural creature, it is a metaphor for self-determination. Sometimes, thinking of things in the third-person is helpful in changing our perspective. Satanism is not about believing that demons exist, it is about repurposing the psychological tools of Christianity to reduce fear and anxiety.

The Satan within you believes in your strength, your beauty, your intelligence.
The Satan within you believes in your kindness, your ambition, your patience.
Believe in the Satan that believes in you! Find that in yourself which is Satanic, and nurture it.
