It's worth getting to grips with rulerships. Astrology starts to make a lot more sense when you can begin to pick apart the avenues of causality that exist within our charts, and rulerships give you this exact perspective.
It's the great conundrum of science and the reasoning mindset that it cannot attune to states of being that are in excess of itself. So science cannot get to grips with love - whether personal or altruistic - except to say something banal and senseless about chemical activity in the brain. The only evidence that can be made in support of love is anecdotal; circumstantial even. The reasoning mind cannot say anything insightful about it at all. Philosophers and great thinkers throughout time have attempted to tackle these thorny subjects. Unfortunately, when Descartes concluded that 'I think therefore I am' he committed an act of genocide on higher states of consciousness for all future generations.
