Shamans frequently use the dense energy of stones on their mesas, or altars and in their healing ceremonies. They are used as medicine pieces to enhance the transfer of healing energies to the one being healed. The word khuya comes from the Quechua word, khuyay, which means to love. Technically the Quechua word for stone is rumi, however, when a rumi becomes a stone of caring or a container of affection, it becomes a khuya. This means it has been consecrated and set aside for a sacred purpose on the mesa. Source: Peruvian Shamanism, The Pachakuti Mesa by Matthew Magee.
