This piece holds an energy that was found in Nepal after fossilized remains to began to show up in the form of seashells in a village called Salagrama. It didn't take long for monks in nearby monasteries to determined that these weren't just any fossils, but the fossilized remains of the ancient God Vishnu.
The monks began using the fossilized remains to develop magic, most notably the ability to open up the third eye. This will give you the psychic ability as the ancient god, Vishnu, who will show you how to access the rest of your newly born psychic abilities. They include psychic healing, the ability to astral travel, the ability to talk to spirits and souls, the ability to see into the future, the ability to move things with your mind, etc.
