It truly is a matter of life and evolution and death, or socialistic stasis. Humans are always in motion. Just as the egg begins to turn when it accepts a sperm, so does the cellular development continue into the cycles we not only have going on within, the microcosm, but are also reflected in the world we see, the macrocosm. The turning of the earth which results in the days and seasons, coupled with the ebb and flow of the moon's gravitational force, turn into cycles and repetitive rhythms in our world. And just as the body reproduces every cell every nine months, this cycle, or definite, rhythmic motion is going on, within, right now.
Every breath takes one closer to home.
But some breaths have great periods of time between them and the evolutionary growth is, accordingly, slower. So, again, one the one hand we have evolutionary negative growth at a slower rate than the other hand's positive, or spiritual, growth at a much faster pace. Eventually the race will be won. That is the resulting logic, or 'given' here. Right now we are in the ending of a period of growth in a certain cycle in our planet and nation's life.
