My daily horoscope told me that I'm in an anxious state because of a "rather volatile celestial pattern that is dramatically affecting your sign" (Virgo). Supposedly this lets up tomorrow.
Generally, I take daily outlooks like this with a grain of salt, but this came from a source that has been insanely accurate for the six months that I've been following. So I am wondering now, what exactly is a volatile celestial pattern? How might I learn more about this?
There's no definition of a 'volatile celestial pattern' - it's clearly a value judgement on the part of the Astrologer writing the column. The only things I can add to ihcoyc's comments are that Pluto is in a tight square to the Sun (37 minutes separating at the time of your post) and Venus is in an applying sextile to the the North Node.
Daily horoscope charts assume that all Sun sign Virgos (in this case) born at sunrise, so Virgo is their first house. The Libra conjunctions are taking place in the second house from this perspective, and that's not really a house relating to anxieties - except in a financial sense - so it might be a prediction about financial concerns. The volatility would come from the Sun/Pluto square and the presence of the Moon, a natural significator of rapid change and of course changes from one extreme (New Moon) to the other (Full Moon).
I'm not a Pluto user, so I wouldn't put any store on the Pluto aspect but I'm in a minority and virtually all psychological Astrologers would take Pluto aspects as of incredibly high import.
