Pumice stones assist in removing toxins, toxic people, toxic energy, and toxic patterns.
Pumice is most commonly known for its ability to smooth out impurities of the skin and removing toxins. Spiritually, it is an excellent absorber of negatively-perceived energy. For this reason, it should be cleansed often. Energy and time is not linear so this may apply to past or present life trauma and issues. It is especially useful in removing negative patterns and karmic ties that prevent you from learning the first time around.
