origin of mayan calendar (6d source, not Ra)

[Plenum]

one question that does not seem to be asked is -

how did the Mayan calendar come to be? why does it end on Dec 21 2012?

I believe that Ra supplies us with an answer: there was a 6d contact made with the south american peoples, and knowledge and information was shared. They most likely left astrological information as well.

23.16 Questioner: I understand, if I am correct, that a South American contact was also made. Can you tell me of the nature of your contact with respect to the attitude about the contact, its ramifications, the plan for the contact, and why the people were contacted in South America?

Ra: I am Ra. This will be the final full question of this session. The entities who walked among those in your South American continent were called by a similar desire upon the part of the entities therein to learn of the manifestations of the sun. They worshipped this source of light and life.

Thus, these entities were visited by light beings not unlike ourselves. Instructions were given and they were more accepted and less distorted than ours. The entities themselves began to construct a series of underground and hidden cities including pyramid structures.

this was a 6d social memory complex, but not of Ra. Ra then confirms the 2012 date in their own communications. (or a close approximation).

17.29 Questioner: Am I to understand that the harvest is to occur in the year 2011, or will it be spread out?

Ra: I am Ra. This is an approximation. We have stated we have difficulty with your time/space. This is an appropriate probable/possible time/space nexus for harvest. Those who are not in incarnation at this time will be included in the harvest.
