I have done some research on this subject.It goes deep.They are more than just scripture,yet it describes the part of us that few know about.
The light of the body is the eye: if therefore your eye be single, your whole body shall be full of light.
But if your eye be evil, your whole body shall be full of darkness. If therefore the light that is in you be darkness, how great is that darkness!
These two Bible verses on their own describe the 3rd Eye or the Mind’s Eye which is the 6th Chakra.It is your Pineal Gland in your Brain.
The Pineal Gland is important.It is possibly one of the most misunderstood if not overlooked part of the human body.It secretes Tryptophan which turn into Serotonin which turns into Melatonin.
Tryptophan is an amino acid that serves as a nitrogen balance in adults and growth in infants.It also creates Niacin a.k.a. B3 which is essential in creating the neurotransmitter and hormone Serotonin.
The neurotransmitter and hormone Serotonin is what regulates your mood and is involved in turning into the chemical and hormone Melatonin which regulates the Sleep-Wake Cycle.
