Ian Xel Lungold in another lecture on the Mayan Calendar:pt 1 pt 2 pt 3 pt 4 pt 5 pt 6 pt 7 pt 8 pt 9 pt 10 pt 11 pt 12 pt 13 pt 14 pt 15
Though no longer here on the earthly plane, he is still the best when it comes to explaining the Mayan Calendar - see Ian Xel Lungold in a long talk: pt1 pt2 pt3 - it's definately worthwhile and somewhat of a "must" for those who want to understand our role and events in a context and bigger picture.
