Change can be observered in states of being. States of being stack in predictable ways. Therefore Identifing the present state of being creates two possible directions things can go. There is a choice available. The state of being unless it is at an exteme can slide in one direction or the other. But once the first choice is made they begin to stack in revercing polarity. This compels choices to be made out of constant, with the originial intent. When a new cycle begins, the primary state of being, becomes the foundation for the entire cycle. The fortune of that cycle, determined by the foundational state of being. To illustrate, I've asigned the fluid state to white, combustion as yellow, solid as red, and gaseous as blue. It's purely arbritrary, but there is a helpfull mnumonic that goes with it. Blue, red ,yellow and white in that order are temper colors. Indicators that energy is changing the state of being of piece of iron. Energy drives change, altering somethings state of being. The extremes are the limits, limits create circulation. White is one pole and blue is the other. White, yellow, red, blue, blue, red, yellow, white. From low to high, high to low, this represents a half cycle. The half cycle creates the mold for the second half to replicate in reverce. The Sun energizes portions of the Earth at a time, creating a rise and fall wave which resembles our pattern above as well as a swinging pendulum, moving from one exteme to another and experiencing changes in it's state of being as changes in force, (weight). This pattern can be applied accross the board to anything or any situation. Because humans take in and expell energy, their process is not revercable. Hence humans can only travel one direction through time.
