Such things do not exist. Organized Satanism is almost entirely a 20th century phenomenon. That means there are no ancient Satanic texts.
In addition, Satanists don't put a lot of inherent value in old things. If an old book has useful ideas, then by all means use it. But being old does not mean being good. Many actively embrace modernity over sentimental historical attachments.
There is no cheat in life. Certainly stories and movies often depict Satanists easily gaining wealth and power through their pact with Satan. That is the traditional Christian view of Satanists. However, such people are mythological. They've never existed. They are the product of fiction, folklore and paranoia.
Actual Satanists are staunch realists. Results require effort. There's no magical shortcut around that reality.
Satanism is about the power of the self. Escaping the bonds of traditional religion, which generally places the believer in a secondary, subjugated position, is a part of Satanic practice. If you expect Satan to command your actions and rigidly delineate your life, organized Satanism is not what you are looking for.
Satanists are skeptics. They believe through evidence and rationality. They do not depend on revealed religion to tell them how to live their lives.
Satanists do not worship the Christian Satan. The Christian Satan is a being of torment, evil and wanton destruction, as well as a being still ultimately subject to God. The Satan of Satanists is often allegorical, and any form of him generally represents freedom, success, pleasure, knowledge and so forth.
Every once in a while a murderer claims to have committed their crime in the name of Satan. These people do not represent the beliefs of any organized Satanic group, and such groups actively condemn such people.
Joining a Satanic organization is more about empowerment and acknowledgement of one's own outlooks than receiving special benefits. Certainly information can be shared, but it isn't secret knowledge hidden away for ages that can only be revealed by a chosen few. Satanists are expected to be self-motivated, comfortable with their own nature, and understanding of Satanic philosophy.
In addition, they actively reject parasitic relationships. Satanists do not waste their time on people who constantly want more than they are willing to give. They also have no time for people who blind themselves with fantastical expectations. Change comes from within, not without. It's about hard work, talent and vision, not mere hopes and wishes.
