I bought and read The Satanic Bible, and patiently waited to see if the big scary sky being would hit me with lightning. When that didn’t happen, I was finally able to let that inner fear pass away.
Yes. Getting free of the visceral belief in a Big Parent in the sky who will punish you for disobedience is not a small part of what this is all about. This is also why performing a ceremonial ritual as a Satanist for the first time and still
not getting "hit with lightning" can be quite liberating.
The same small child we all once were can be afraid of the dark and feel intimidated by the adult giants he remembers. To stand up straight in a darkened ritual chamber and declare yourself as you are, as your own God, addresses this deep-set part of the mind and is also a declaration of adult maturity.
Congratulations on your insights and welcome to the board.
