Venus Square Pluto...

enters on March 11 (using a 1 degree orb), is exact on March 12 at 4.36am in Kilmore, leaves on March 13.  Venus at 5 degrees and 14 minutes of Aries, Pluto at 5 degrees and 14 minutes of Capricorn.

Intensity!  That's the first thought that came to my mind when I thought about this aspect, especially in the fiery Aries and structured Capricorn. 

Venus is about the way we attract what we want into our lives, and also represents our values, women, affection, pleasure and fertility.  Pluto transforms whatever it is involved in and usually evokes quite a strong emotional response.  The combination of these two energies via the square suggests tension because the energies are working at odds with each other (both planets are in cardinal signs so both want to be 'boss'!).  I feel that Pluto is the stronger of the two, so Venus will most likely have to do the compromising.

By looking at where this square is happening in your birth chart you can get a feel for where you have the opportunity for a turning point.  Also look to see which houses are ruled by Venus (ones with Taurus or Libra on the cusp), and Pluto (ones with Scorpio on the cusp).

If you have personal planets or points in Aries and/or Capricorn you are likely to be especially sensitive to this transit.
