I cant remember exactly where I found the original information from? I thought there was something on astro that explains all their charts ,hmmm perhaps not!?
But yea ,when a chart has two separate final depositors energies work differently.So for example with Ralphs moon ,there is no other planets in a chain before or after the moon so the energy here is more of a pure state, although we remember that the aspects to the moon are crucial too.the way I look at it is ,if we see all the planets as being parts of our phyche we see that mars for instance represents how we deal with anger,when that part of our phyche is stimulated we then see how that energy then becomes dilluted and changes through the aspects with other planets and in the depositor tree.for example the mars energy may be channeled into the next planet which will then add its charachteristics into the mix.
