What Are the Three Brains?
"Perfect mental equilibrium is of vital importance for those who want spiritual progress. Almost all the aspirants of esotericism easily lose their mental equilibrium and usually fall into the most absurd things. Whosoever yearns for direct knowledge must ensure that their minds are in perfect equilibrium... Mental disequilibrium is avoided by balancing the three brains." —Samael Aun Weor https://glorian.org/connect/blog/three-brains-and-five-centers
