The pineal gland begins to harden with calcified tissue starting at adolescence. These strange calcified deposits between 3-5 mm are called “brain sand”. There are asymmetrical crystals in the pineal gland that are ‘piezo-electric' - that is, they send out electronic voltage creating EM waves. Whenever a person is exposed to an EMF (electro-magnetic field) such as that of the earth the gland vibrates, sending out EM signals to the rest of the body. When the pineal gland is stimulated geomagnetically it produces alkaloids similar to plant psychedelics. Any strong change in the earth's EMF will produce a rush of psychedelics in our bodies enabling us to be more psychically active in shamanic states (earth/ land receptive). The pineal gland is effected by coherent EM fields and it changes its hormone production when exposed to EM at low levels. As the earth has the greatest effect of any force on our physiology it makes sense that the cells of our body and brain align with it. All life within the envelope of earth's vibrational influence attempts to match base-frequencies (entrainment) with that of the earth. To this end, each of our cells is constantly shifting patterns of energy to achieve harmonic resonance with the reference signals of our earth. Our bodies are truly amazing and they are intimately co-dependent with the earth and all its inhabitants. Our bodies are miraculous organs of phenomenal complexity and awesome ability. We are made up of multiple trillions of molecules, each vibrating with its own intelligence, all interlinked just as our universe is interlinked and interconnected. We reflect the whole. A picture may be beginning to emerge as to how we reach shamanic states through the wisdom of our body in tune with the earth.

When we experience a shamanic journey our pulse rate increases at the same time that our blood pressure drops. This is also what happens as the body is preparing to die. As the life-force leaves our body through the pineal gland, another flood of DMT is released. I believe that the initial stages of a shamanic journey replicate this near death experience and so triggers DMT release in the brain.
