Since ancient times the serpent has symbolized wisdom, death, and resurrection, which is perfect because this piece does all three for you. In early mystery schools of mysticism, the serpent was akin to "the Word", which is the knowledge and magic God used during the creation of Earth. The "light" that appears with "the Word" (aka Arcane Knowledge) is defined as the Kundalini Serpent that lies dormant in an unawakened person.
What this piece does is gives you an awakening of white light. This will release your Kundalini Serpent that lies at the base of your spirit being, waiting to be uncoiled to spread the Word and pure knowledge within your body. This will release your inner Godhood and your latent abilities of magic and psychic power will come to full fruition. What abilities you get will depend upon yourself because god had hidden a different type of Godhood in all beings. However, everybody has them and they are waiting to be awoken. That's what this piece does.
