It is important here to grasp that Saturn is the realm of form and time, the planet of all physicality, similar to the form of our body that contains all the organs, and in this case all the planets within Saturn, including the great Sun, which of course is not a planet. Saturn is this physicality and form.
Just as we know that Mars has to do with drive and energy, Jupiter with direction and path, so Saturn has always been the planet of form and the physical. It is not enough to simply nod your head that you understand this concept and move on. If it does not deeply register, then what follows is not going to make much sense to you, the fact that the outer planets are not physical, are not physical places or stages. In the context of Shamanic Astrology, these outer planets are beyond form and the physical, thus: meta-physical, the measure of the physical, the sensing of the physical – a mirror.
Astrology here is but a language. We are not talking about putting a space probe on Pluto and sampling soil, but instead we are using astrology here to point to the esoteric meanings of the planets, in this case the outer planets, Uranus, Neptune, and Pluto. Astrology is only a language we use to point to something happening in our lives, and not itself much of an end. Shamanic astrology does not have to correspond exactly to other forms of astrology or to science. There are many astrological languages, and the point is to make them articulate and speak to us.
