D13: The Pineal Gland

The Pineal Gland is regarded as one of the most important parts of your nervous system.
It is shrouded in mystery, but as more and more people investigate it they are realizing it is essentially a spiritual antenna, the mystical third eye that ancient traditions have been talking about.
For many eons, the third eye has been seen as a way to reach higher levels of consciousness while still being present in a physical body.
