My understanding is that offering freely is about the giver and means my giving is my choice and what is given is a gift from me for which I expect nothing in return. Offering for free is about the receiver who has no obligation to pay for what is given. Who, when, and how much I charge for something that I give is arbitrary. There are times and people for whom I have chosen to give freely. We all do some of that, usually giving freely of ourselves in small ways that are important. What helps me stay rooted in abundance is to remind myself daily that life is a gift, that I have been given very much and that it only makes sense for me to give from what I have been given, that I am part of all that is and thus really own nothing, that the other is me in a way that is beyond my understanding, that giving is natural, that I feel joy in giving and feel better giving than receiving. I come from a pace of not being very giving, and becoming more giving over the years has been a more satisfying way to live.
