The Sun in Virgo opposes Neptune Rx (at 6 degrees Pisces) from August 27th to 29th. This is the tension between logic (Virgo) and fantasy (Neptune). Perfection versus transcendence. Both Virgo and Pisces seek to elevate themselves through refinement. Virgo seeks to refine earthly details, and Pisces seeks to refine what cannot be touched. This opposition asks if Virgo's efforts are futile in the face of Neptune's larger truth? Or, are Neptune's dreams futile in the face of Virgo's facts?
Any opposition to Neptune (transiting or natal) will confront you with the pull between what you know versus what you aspire to. Can you rise above your fears, or will you lose yourself in the addiction/dream? Will you dissolve what you've built up, or take a leap of faith?
These are all Neptune opposition questions. If you have this aspect natally (or are in the midst of a long-term opposition from transiting Neptune) you'll recognize the constant dissolving and solidification and dissolving that accompanies this influence. You are at the crossroads between spirit and earth. The final answer (what's right for you) depends on your chart.
You'll feel this influence most strongly if you have anything from 4-7 degrees of the Mutable signs.
