Dr. Jacobo Grinberg (1946–1994?) was a Mexican neurophysiologist and psychologist whose work bridged the gap between science and mysticism. His books are highly sought after for their exploration of consciousness, meditation, and the "syntergic" theory of reality.

But he would also have been frustrated. Grinberg valued precision. His diagrams of neural fields are illegible in most free PDFs. You lose the information density.
