I've noticed lately when I project that my heart chakra has been beating (vibrating? don't know the word for it) like crazy. Since this has started happening, throughout the day I've been getting pains in the same spot where the beating is coming from. I've also noticed a warm feeling there occasionally. I'm just curious if this is related to my heart chakra, or if it's all in my head, or related to something else. I've noticed though, whenever I'm grateful, or at night when I think about everything I'm grateful for, I get this very sharp tense feeling where my heart chakra is at. Why?
