History repeats itself! Why? Because the ego based mentalities, attitudes, behaviors, habits and actions are followed and continued from one generation to another. When we quote ego based reactions from History and follow them, we reinforce their energy and give them power which are then followed by future generations. This often requires a deep ancestral healing to break free of it.
Response from any form of ego will surely have consequences which are also ego based. Even if the form of consequences is different, the energy will be essentially of a same vibration. History will stop repeating in families, organizations and society at large when people at the individual level in a family or collectively in a society/country start to live consciously as souls and not this body/mind.
