Gyres Field Guide Vol 1 - The Crystal in Your Skull

There really are crystals in your head.

Not in the sense the Internet means it. In 2002, researchers examining human pineal tissue found microscopic calcite crystals - the mineral of chalk and seashells - with a structural asymmetry that can, in principle, generate a small electrical voltage under pressure. The measurements are real and published. What they mean is another question entirely.

This guide takes that finding apart honestly. It explains the physics of piezoelectricity in plain English, walks through exactly what the pineal research did and did not establish, separates the genuine measurements from the layers of claim that have accumulated on top of them, and states plainly what evidence would change the picture.

Then it does something most books on this subject will not. The author, who has meditated for over 50 years and practices his own form of energy work, describes his own experience - clearly labeled as experience, with the ordinary explanations stated before the extraordinary ones.

Four labels. No blending. You always know what you are reading.
