Exactly if someone has the means to do so without having to charge, great.
But we all have bills to pay and someone can either work that into a profession to help people or not do it.
My friend does Reiki. She's very good at it, but because she's so afraid to take money for doing it, she keeps her day job and only does a few people when she can fit them in.
What a waste, all because people who think that because it's a gift, they shouldn't charge.
