Fire is one of the four classical elements in ancient Greek philosophy and science. It was commonly associated with the qualities of energy, assertiveness, and passion, while earth was commonly associated with qualities of practicality, restraint and materialism.
Lava rocks embrace both elements. Red and black lava rocks are a wonderful tool for the Root Chakra. The can be used for grounding, protection and making a connection to the earth.
