[WH40K] Do Daemon Princes and Greater Daemons communicate directly with their patron gods?

So when a dude becomes a Daemon Prince, do they receive communication straight from their patron god? Or do they just suddenly gain power? Do Greater Daemons just have "standing orders" and/or do things that will give their patron gods power, or do they communicate directly with the god in question? 

Is it a one way line, like you ask for Favor from your god and you do things that you think will get that, and you get that favor if you do it right? Or do you get direct speech from the god on what do to?

Yes. After a fashion. It's rarely in the form of a conventional conversation, and typically in a communion of wills and though, but mortal champions and Daemon Princes alike can commune with their patron. Particularly profane rituals even allow the summoning of messenger-aspects of warp-entities which can usually hold a conventional conversation. 

Greater Daemons are somewhat different. They are both independent Warp Entities of near infinite power, and parts of the greater whole that is their patron. Speech between Khorne and a Bloodthirster is never as a mortal would understand, but rather an expression of wills. Sometimes, lime with Skarabrand, the servants will is resistant to that of its greater master, somewhat like a numb limb refusing to obey the commands of the brain.
