O how the mighty are fallen

Imagine that a being from an advanced culture gave you a toy designed to both entertain you and instruct you in the workings of our reality matrix. The toy works like this: at any moment, you can freeze the flow of time into a very small slice which not only tells you the nature of the moment, but why you chose it, the ramifications of having chosen it, and three other co-ordinates of change that create the moment and the choice.

Essentially, the I Ching, the gift of Fu Hsi, is such a toy. Any means of random selection can be used - counting yarrow stalks, tossing coins or a binary computer program - to provide the hexagram which marks the quality of that moment. This hexagram is then interpreted by various methods and then related to other hexagrams to provide an inclusive and holistic perspective on the evolution of that moment in time. The value of such knowledge, however, comes from our ability to make use of it.

According to this view, all of biological and cosmological time is approaching a point of concrescence in the near future. The McKenna brothers went looking for possible dates for this concrescence and decided that the helical rising of the winter solstice sunrise in 2012 matched the requirements.
