Today the earth’s celestial equator (the earth’s equator projected into space) passes through the sun’s ecliptic (the sun’s apparent path throughout the year, actually caused by earth’s orbit.) You usually hear this put the other way around; that is, as the sun passing through the earth’s celestial equator, but that represents the stuckness of paleolithic astronomy that assumed the earth was the center of the solar system. From the diagram above you can see the sun’s declination (degree above or below the celestial equator) is 0 on the vernal and autumnal equinoxes.

This same diagram is very clear about the solstices, too. You can see that when the earth’s orbit tilts the northern latitudes toward the sun, the sun is highest in the sky-the summer solstice.  When the sun is lowest in the northern sky-the earth tilts away from the sun and gives us the winter solstice.

Since the summer solstice day time has exceeded night time. In theory the autumnal equinox is the point of equilibrium between light and dark, but at our latitude that day actually occurs on September 25th this year. This is, however, the day the Great Wheel celebrates and it does so because of the sun’s zero declination at earth’s celestial equator.

This week then the victory of the sun, made complete on the summer solstice, begins to wane. The dark god of deep winter gains greater and greater authority as the sun’s rays spread out over a larger area of earth, thus weakening them, and the number of hours that the sun is in our sky, even in its weakened condition relative to the soil, decrease steadily until the night of the winter solstice. Thus comes the fallow, cold time.

It is no accident that the harvest season is now. Over the 475 million years (give or take a hundred million) since plants made it out of the oceans and onto land, plants have adapted themselves to the conditions that work with their particular genetics. Key aspects of a plant’s life include carbon dioxide, soil nutrients, available fresh water, adequate sunlight and temperatures adequate for all these to work with the plant’s life cycle.

Thus, as the earth’s orbit carries it to different relationships with solar strength, temperatures change along with it.  At its maximum when the earth tilts toward the sun and the sun is highest in the sky, the sun’s rays fall on a smaller area of land. Here’s an excellent simulation. University of Nebraska-Lincoln.

Plants have had the past 475 million years to refine their growing season so that it takes maximum benefit of the sun’s strength. In a very real sense the growing season is a clock, or an astronomical observatory directly correlated to the earth’s orbit around the sun–The Great Wheel.

On a spiritual level, if we follow the ancient calendar of the plants, the season of external growth, flowering and seed making, is waning now. Just as the plant either dies out and anticipates its rejuvenation from scattered seed or goes dormant and waits with stored energy below ground in roots or corms or bulbs, so we might consider this season as the one where we shift inward, away from the external demands upon us and the expectations put on us there.

Now we shift toward the interior life, the Self becomes more of a focus, our spiritual life can deepen. We can see this shift in the human life cycle if we compare the second phase of life with its emphasis on family creation and nurture and career, to the third, with its pulling back from those external expectations. The third phase is a post growing season time of life, not in the sense that growth ends, but that its focus is more down and in rather than up and out. The third phase is the fallow time.  Michaelmas on the 29th of this month is known by followers of Rudolf Steiner as the springtime of the soul.

The third phase marks the beginning of the springtime of the soul for the individual.
