The topic of ceremonial forms for the outer planets came up in a discussion last week. So I figured I would put together a quick overview of how I attribute the outer planets and what I would do to work with them in a ceremonial context. There is not a lot of agreement on this topic, and I have heard of a number of different schemas being employed by different practitioners. As always, keep in mind that if you have something that works better for you, keep doing that. My first rule is that if it works, it works.
At any rate, I'm not a fan of Aleister Crowley's final set of attributions for the outer planets, in which he maps Uranus to Daath, Neptune to Chockmah, and Pluto to Kether. If you're going to use Kircher-style planetary attributions for the sephiroth above Binah at all (and, to be clear, you don't have to if you prefer different attributions, or would rather drop the planetary attributions for the sephiroth altogether), it seems to me that the astrological natures of the planets really don't fit all that well. Mapping the higher octave of Mars to Kether and the higher octave of Venus to Chockmah don't make sense to me, even if you can make a case for the higher octave of Mercury as Daath.
Better to my way of thinking is the pre-Pluto system found in Crowley's General Principles of Astrology, where we find Uranus mapped to Chockmah and Neptune mapped to Kether. As modern astronomers have worked out, Pluto is the problem. It's not a "planet" in the same sense that Uranus and Neptune are. It is a Kuiper belt dwarf planet, and not necessarily even the largest one. Keep in mind that doesn't mean I think Pluto is astrologically irrelevant or anything like that. I just associate it with "asteroids" like Ceres, which is now considered another dwarf planet. Astrologers find the asteroids significant, too. They make aspects just like the larger planets do, and can be highly relevant when interpreting a chart.
