" The Satanist realizes that man, and the action and reaction of the universe, is responsible for everything, and doesn't mislead himself into thinking that someone cares. No longer will we sit back and accept "fate" without doing anything about it, just because it says so in Chapter such and such, Psalm so and so - and that's that! The Satanist knows that praying does absolutely no good - in fact, it actually lessens the chance of success, for the devoutly religious often sit back complacently and pray for a situation which, if they were to do something about it on their own, could be accomplished much quicker!
The Satanist shuns terms such as "hope" and "prayer" as they are indicative of apprehension. If we hope and pray for something to come about, we will not act in a positive way which will make it happen. The Satanist, realizing that anything he gets is of his own doing, takes command of the situation instead of praying to God for it to happen. Positive thinking and positive action add up to results.
