I don't know about chakra work beyond which YouTube has taught me. LOL. But when I meditate I get a tickle in the back of my throat, making it almost impossible not to cough. I'm fine most of the other time, so I'm hoping something like the apatite will open that chakra for me. I think it's a side effect of my high blood pressure medication but it's odd that it only happens when I meditate.

Either way, it's a pretty blue and that's enough for me. LOL.

Sounds like you and the cards are a good match. Have fun with them.
