You can find out for yourself. I advice to advance, clean yourself before working with a god, and consider a 100 times what do you want to give back in return to the given god. It's probably won't do anything good if your first work, or mediation is to ask a god to do something for you.
You offer something and if you don't get a bad feeling or some sign that it is not enough, then it is enough. You can offer your energy too, but if you do so, then do meditaions that rise your energy back.
Also beauty inhance sounds really hard to do, but if you are in your teenage times, maybe it is possible.
