Rob tells Virgos:
In the language of the Hopi Indians, koyaanisqatsi means “crazy life,” “life in turmoil,” or “life out of balance.” It’s usually invoked to describe a culture that’s in disarray because of corruption and lack of vision. In the horoscope you’re now reading, however, I’m using it to identify a chaotic state that each of us periodically goes through in our personal life. It’s a phase when we lose our moorings, when we’re out of touch with our moral center. On the one hand, it’s uncomfortable and disorienting. On the other hand, the brain-scrambling it stirs up is often a blessing. It flushes out mental habits that no longer serve us. It provokes creative innovations by rearranging the contents of our psyche. According to my reading of the omens, this is such a time for you, Virgo. Happy koyaanisqatsi!

He tells Libras:
The muskmelon is a fruit that continues to ripen after it’s picked, whereas a watermelon stops ripening the moment it’s plucked from the vine. As you enter your own personal harvest season, Libra, keep that difference in mind; it’ll be a useful metaphor. Some of the “crops” you’ve been growing all these months are like muskmelons, while others are like watermelons. Do you know which are which? Let the watermelon-like fruits of your labors stay on the vine until you’re absolutely sure they’re fully mature.

Both of them seem kind of random for me.
