In locational astrology, a paran is a line that circles the earth latitudinally. Each paran has an origin point: a location where two rising, setting, MC or IC lines intersect. It is from this parallel that the paran line emerges east and west, like a ribbon around the globe. Any paran’s orb of influence is up to 2 degrees north or south of the line.
I recently left Minneapolis, MN, on the 44th parallel North, where I lived for 18 months. I have a Mercury rising/Pluto rising paran passing right through Minneapolis, and learned a good deal about what this meant for me by living there and observing its influence.
