Hmm. Okay.
Entities themselves do not follow us, unless commanded to..which they must be programmed to do. Strong beings are harder to program, and in general, don't bother. If you mean thoughtforms you make, you make them and help them achieve whatever their goal is. If you mean what the enemy sends against us, that can be repelled, which is a good thing.
Being a Satanist is understanding Father Satan, alongside the Nordic Demons (on the Joy of Satan website) to be our creators and, I lack a better word, "superiors." Father Satan made us, specifically of them all, and watches over us. But, the Demons (which means "a god") want us to become like them: powerful, immortal, with a "risen serpent and elixir of immortality". More on those two can be found on the website. No, it's not inherently easy for most, but it's our goal as Spiritual Satanists. And we're Spiritual Satanists specifically, that extra word is vital.
Lastly, Father Satan and the Demons are our origin, so they look after us. The enemy, the Jews Greys Angels and Reptilian-things, want us dead because they do..they see us as a threat and have been fighting Father, though they lost, for a long time. Father's defeated the main branch of the enemy, but those who remain on/near Earth, simply, "haven't gotten the memo," or more accurately, are destroying what they can before they die.
Any more questions? Reply here. I only speak English or I'd be happy to convert this into anything. If I used a phrase you don't understand, I'll try to explain it better; I can use idioms, colloquialisms, and other statements that don't translate well.
As for how it benefits you, you can become immortal and develop cool powers, but MOST importantly, you can understand mankind's past...you can see past the lies. True enlightenment, true sight, true understanding..if wisdom is your cup of tea.
