Ah! Dominic, The Great Ones! Who be they? and Where be they?
They are the ones who thought outside of the box, outside of the tribe. They came with a mission, a great purpose, to advance mankind. To give to struggling humanity new ideas, a new vision. To inspire, to light the spark of Freedom.
Unfortunately, they were vilified, hunted, shunned, murdered. Their gifts to humanity were usually recognised long after their passing. Humanity's level of consciousness had to advance considerably to understand to any degree, and advance even more to accept the knowledge given. They came from the future to advance the present!
To name some ; Jesus of Nazareth, Budda, Pythagoras, Appolonius of Tyana, Einstein, Neils Bohr, Victor Schauberger, Nicolas Tesla, Peace Pilgrim, Handel, Tolkein, Shakespeare, George Washington, Joan of Arc, etc, etc etc.
I do not know who were Masons but some of them were. And where are they? In the dimensions beyond this one.
Actually, there are two answers to your question. The other Great Ones are Us, only now wiping the sleep from our eyes and questioning the Tribal edicts!!!!!!
Love
Carmen
