“Consider, for example, the sun: its transit from one zodiacal sign to the next occurreth within a short period of time, yet only after a long period doth it attain the plenitude of its resplendency, its heat and glory, in the sign of Leo. It must first complete one full revolution through the other constellations before it will enter the sign of Leo again, to blaze out in its full splendor.“
