This planetary correspondence is like nothing I have ever seen before, too.
As I was meditating on your comments, I refleced on the 6 O'clock line and Cancer. Cancer is relegated to the base-of-the-spine and there is a relationship between Uranus and Cancer, however remote. What we (astrologers)know about Uranus is related to its discovery, during the industrial revolution and therefore it has been related to the new wave of science and technology, aviation and electronics, among others. These seem to be masculine qualities, yet they are, in fact, feminine.
We know from the SU teachings that technology is 'mother.' There is a relationship between the Moon (the ruler of Cancer) in considering again the 6 O'clock line and Cancer. If we link up the Lunar rulership of this sign, esoteric astrology says that the Moon is a veil that either hides the planet Vulcan (an intramercurial planet) or Uranus. According to Esoteric Astrology, instead of using the Moon, Vulcan is to be used in the horoscopes for average humanity and Uranus for disciples. In other words, the Moon is considered, a blind or veil. If we consider the fact that we are spiritually awakened then this Uranian connection with Cancer is appropos.
Thus, we may have one idea as to how Uranus can be related to Cancer and the base chakra. Also, there is another corespondence to Aquarius, the sign that Uranus rules, and it is related to the Moon, as the primary ruler of Cancer and the Moon as the hierarchical ruler of Aquarius; in this case the Moon relates the two signs, because of this relationship.
I am relating the current chakra associations with the cosmic clock and with esoteric astrology stuff. The question, for me is whether these correspondences are for us as disciple/initates, whereby there is another planetary scheme for average humanity.
