The Sun in our Vedic Birth Chart is the Charioteer who drives our Chariot of Self. He holds in his hands the reins that go to the horses that pull the chariot of self: these horses are the other planets. There are big problems if the horses are stronger than the charioteer, or if they are not all guided in a chosen direction. With a weak Sun Charioteer, the stronger horses/planets can take over at different (predictable) times, and this can mean a different person is projected at different times, which is so confusing for the self and for the others around you.
I combine Vedic Astrology with psychodynamic western astrology. For details of my astrology readings and astrology distance courses see: www.starwheelastrology.com
My recent book: The Backpacker’s Guide to the New Spirituality 2014 is a wonderful spiritual book with linked distance courses, see Amazon paperback or kindle
