Hello Astro7,
Both the SN and 12h show past life material, but are a bit different.
The 12h is the main karmic house in the chart, and shows the debits on the karmic credit card. Planets in the sign have very heavy karmic connotations. They are showing the results of past actions, personal or collective. 12h is showing the issues the soul is dealing with, and drives or the unconscious which must be balanced.
If the house is empty, look to the sign on the cusp of the house, the placement of its ruler to give indications of karmic pattern. It is a clear request to resolve the karma in this lifetime.
The NN shows purpose, evolution and present and future progress.
The SN represents past deeply ingrained patterns of behavior, past lives, all that has gone before. The goal would be to take the good traits of the SN sign, and leave the negative ones behind.
Talents brought forward from past lives would be the 2h which is the karmic gift house, a credit on the karmic charge card. But easy aspects are also showing talents and gifts as well.
The Sun conjunct the SN means that the soul has been working on the sign energy in other lives, and is meant to refine the positive energies of the sign and use them in a constructive way towards soul growth, capitalizing on skills acquired in past lives. And yes the SN can be a comfort zone, and cause stagnation. But there are energies and abilities from the SN to incorporate into NN work.
12h Moon indicates karma with mothering or being mothered. The sign will give you the type of issue around mothering. Rejection and abandonment issues may be present. It can also indicate problems with emotional issues.
Yes, the Sun and Moon are karmic markers, the Sun is present life, the Moon is past lives.
The fact they are placed in the nodal axis or 12h is a strong message that you are meant to work on the karmic issues being shown.
One way that karmic astrology differs from TA, is that we don’t move planets around in the chart. This is somewhat horrifying to me when I see this. The soul has taken a great deal of care, preparation, and planning when deciding upon the exact time of birth and location, in order to receive the cosmic dusting necessary to achieve certain goals and lessons.
So KA play it as it lays. If you have the exact time of birth, make sure your moon is in its correct house. I would interpret your Moon as in the 11h. That interpretation is about friends and group karma, and the moon placed there would be about women, nurturing, etc.
Hope this helps.
