In this fascinating interview Dr. Greer articulates the dangers of being an interplanetary specie without a peaceful disposition. This would actually be worst then, because in that case humanity would export war outside our planet.
Therefore, even more important than Free Energy and Anti Gravity technologies, is a peaceful and compassionate disposition and recognition of every cosmic conscious beings as our brothers and sisters, not only on this planet, but everywhere.
This unfortunately is not happening yet on this planet alone, and it’s a very important aspect on which we all can improve as a whole.
