Meaning of Pinecones:
"Throughout the span of recorded human history, Pinecones have served as a symbolic representation of Human Enlightenment, the Third Eye and the Pineal Gland.
Our “Pine”al Gland, shaped like (and named after) the Pinecone, is at the geometric center of our brain and is intimately linked to our body’s perception of light. The Pineal modulates our wake-sleep patterns and circadian rhythms, remains uniquely isolated from the blood-brain barrier system, and receives a higher percentage of blood flow than any other area of the body save the kidneys."
