This unique stone is sourced only in the Narmada River in India. It's often found naturally shaped by the water in this oblong shape, in which case it's referred to as swayambus, Sanskrit for "self-manifesting."
People associate Shiva Lingam and its phallic shape with its ability to awaken Kundalini energy that's present at the base of the spine. Upon uncoiling this energy, it's said that great enlightenment is achieved along with overall balanced energy and elevated consciousness. A sense of oneness and connectedness with the Universe.
Shiva Lingam is in a category of its own with its reported abilities to induce great calm in meditation, help shed guilt relating to sexuality and enhance its experience, purge self-limiting beliefs, and strengthen our connection to the Divine above and the Divine within.
You won't find many stones with a reputation like this one.
