The planet which rules me, is unfortunately, Saturn.
Saturn is the planet of Karma and thus it 'rules' everybody to a greater or lesser extent.
My natal Saturn just happens to be retrograde in Pisces in the Third House.
This has caused me no end of trouble throughout my life.
There is also this thing inside me which occasionally says that I need to have another "Shani Puja" done - a ceremony to ward off the malefic effects of that planet.
