Ra Material: The Law of One & History:
This occurred approximately 500,000 of your years ago.
The other race is that being offered a dwelling in this density by guardians who wish to give the mind/body/spirit complexes of those who are of this density at this time appropriately engineered physical vehicles, as you would call these chemical complexes, in the event that there is what you call nuclear war.
There are three types of Bigfoot, if you will accept that vibratory sound complex used for three such different races of mind/body/spirit complexes. The first two we have described.
The third is a thought-form.
The escalation went to the furthest extent of the technology this social complex had at its disposal in the space/time present of the then time. This time was approximately 705,000 of your years ago. The cycles had begun much, much earlier upon this sphere due to its relative ability to support the first-dimensional life forms at an earlier point in the space/time continuum of your solar system. These entities were so traumatized by this occurrence that they were in what you may call a social complex knot or tangle of fear. Some of your time passed. No one could reach them. No beings could aid them.
Approximately 600,000 of your years ago the then-existing members of the Confederation were able to deploy a social memory complex and untie the knot of fear. The entities were then able to recall that they were conscious. This awareness brought them to the point upon what you would call the lower astral planes where they could be nurtured until each mind/body/spirit complex was able to finally be healed of this trauma to the extent that each entity was able to examine the distortions it had experienced in the previous life/illusion complex.
After this experience of learn/teaching, the group decision was to place upon itself a type of what you may call karma alleviation. For this purpose they came into incarnation within your planetary sphere in what were not acceptable human forms. This then they have been experiencing until the distortions of destruction are replaced by distortions towards the desire for a less distorted vision of service to others. Since this was the conscious decision of the great majority of those beings in the Maldek experience, the transition to this planet began approximately 500,000 of your years ago and the type of body complex available at that time was used.
