interesting points, Barleywine. Just like with a psychic reading/medium reading, and any other form of divination, one should always protect and ground themselves. Sometimes people don't think this is necessary to do so, but yes, it really is, I guess.
Any form of divination can bring spirits or who knows what through to us. So, we should always be careful and take the proper steps to being safe before participating in any form of divination. Thank you for the reminder. I did have a look at your spread and I like that too. But, even in this case, it may still be best to protect and ground oneself before any reading of any kind. Asking our guides to always watch over us and protect us from anything/anyone harmful is just one small simple way of protection, or you can take whatever forms of protection and grounding that you feel is necessary. And, perhaps we should do this. Though, I admit, I don't usually think of doing this when I am reading cards. Not sure why I don't, as I do it before scrying, (which I don't do much of) and before any psychic or medium reading. Maybe I should though, eh?
