The world, as we use to know it, will not end. The world as we're trying to adjust won't end as well.
If anything, anything that has a person doing something that mal-aligns w/well, your Soul...I'd say, for this moment n time and to even contemplate such a thing...stop doing it.
I feel strongly, the Mayan calander ended at some point, in time, back then, for a reason, and unbeknownst to us.
We really weren't there, to bring into this day and age, something of relevence or doctrine and act by it.
I feel we'll go on with many more calanders to follow. As well, we'll have many more things to celebrate.
