^ Sounds like slavery for the human, this is why so many people are drawn to chakras and such, they have the powers with in them to do the things that spirits do so they won’t need to be dependent on the dameon or anything else. That is my main goal on this path.
There are spirits you can work with closely who will ask a lot, if you’re up for it, but also give a lot more - they’re not all cosmic moochers. 
It’s like any relationship, it’s cool to be putting a lot in so long as you’re getting an equal or greater amount of what you need back, but that’s totally possible to have.
