I come from a spiritual family. Tarot readers, coffee ground readers, dream interpretation. My grandpa a shaman too. You know where I go with this. I do believe we are energy. I do believe anything inhabiting earth has energy and a purpose. I would not call it placebo effect but it is true that if your mind does not connect with your heart, there will be no frequency between you and a stone. We are the medium to power anything we want. But we must believe. Just like in religion, sometimes when we believe with all of our heart and mind, the power of faith moves mountains. If we believe strongly and faithfully, is my understanding that we will connect with the whatever item, a rock, a piece of bark, a healing desire, anything. Our frequency would be so in tune that would change things right in front of our eyes. Is my personal opinion.
