All the beginnings of cycles begin with a conjunction. Then, as it progresses through the zodiac, the fastest planet of the two is in aspect with the slowest. It produces a sextile, then a square, a trine, an opposition. This done, and while continuing its course, the fastest planet forms a second trine, another square, another sextile and a second conjunction. The slowest continues its work.
