Sf you don't know the pineal gland, know that you all have it. This little gland well hidden in your brain, just like the pituitary gland, has incredible powers that can considerably influence your life. As the name suggests, it looks like a small pine cone in the center of your head under the brain and at the top of the brainstem.
Ancient cultures tended to represent it as a third eye, more precisely Horus's eye.
