What happened on this place on the cosmic Wheel of Time long ago that leaves me feeling like I've just experienced some sort of devastation?
What you're feeling, has not happened on this day on the cosmic calendar, but rather it has happened approximately every 350-400 years on our solar (Gregorian) calendar in repeating cycles. The most recent of these events happened on the 26th January, at 9.30pm at night in the year 1700AD.
The underwater volcano erupted in the Pacific Ocean, generating a tsunami that wiped out the West coast of North America for hundreds of miles inland and even effected parts as far away as Japan and other areas of what is called 'The Ring of Fire'.
The Cosmic Wheel of Time
Approximately 180,000 years ago, a footprint of trauma was left on the cosmic wheel of time, by this same underwater seismic zone — resulting in the activation of a string of underwater volcanos. The event caused the largest mega earthquake and tsunami ever experienced on Earth that reshaped the geography of the Southern Hemisphere. You are also feeling the awe and shock of the planetary inhabitants of that time.
What can we do to ameliorate such an event?
I live like a hermit and am not familiar with current events. But the Angelgods have told me that the number of global volcanic eruptions have notably decreased since the Original Ones have awakened to who they are.
When an Original One expresses his or her authentic feelings with kindness and tact, instead of bottling it up until it explodes, it allows the subterranean pressure to gently release rather than to erupt in a destructive way.
