As Alan Watts once put it, 'Most people who call themselves Christian don't practice the religion of Christ, they practice a religion about Christ - which is of course not the same thing'.
I went through a 'Satanist' phase that lasted about 6 months when I was in my late teens, but I then moved on to the works of Aleister Crowley which seemed much more conducive to making progress in my life at that time, and also a bit more intellectually robust, especially with its grounding in yoga. The Satanism didn't seem so relevant when I left the home of my vaguely Catholic upbringing and got out into the real post-Christian world. Satanism may be more relevant and useful in the USA where religion still holds real and potent power in politics and the lives of people.
For anyone unfamiliar with Crowley:
Liber Jugorum & Liber E. You may want to try the excercises out of curiosity.
