Okay, I found this really cool way to pray to Lucifer.
It has 4 steps:
1. Greetings
2. Praise
3. Request
4. Conclusion
Greetings is something as simple as saying "Hail Lucifer" or "Reggie Satanas".
Praise is a bit more complicated. You can say something like "Lucifer, you have helped me and because of you I accomplished my goals before". This praises Lucifer.
Request is basically what you wish to happen now. For example, if you want money, say "I request money for the fullfillment of my new goal".
Conclusion is basically you saying something like "And so let it be done".
So the prayer would go:
"Reggie Satanas.
Lucifer, you have helped me and because of you I accomplished my goals before.
I request money for the fullfillment of my new goal.
And so let it be done."
