Doreen Agostino shared this as a Comment: “The vibratory frequency of anger is 150 hertz. Courage is 200 hertz and the threshold to enlightenment [unveiled]. When humans transform anger/revenge into heart intelligent courage for our collective good, best possible solutions are empowered to set us free.”
The chart below, also suggested by Doreen comes from GrowthGuided.com. It is David Hawkins Map of Consciousness.
David Hawkins Books are also interesting. My favorite is Power vs. Force.
