During periods of equinox alignments, the days and nights are of equal length. I can remember standing on specially designated points at ancient ruins during this day, seeing the sun on my left and the moon on my right, both at the same points in the sky. The experience of balance and neutrality was indescribable. It is during an equinox then, that energies can “cross over” and move about, as there is no uphill or blockage prohibiting this movement, but only a straight and flat road.
