In the 17th Aethyr, TAN, you get your first look at understanding karmic balance and activating the process to balance your own karma. Karmic forces can be found in every Aethyr below LIL but in TAN the energies are especially strong to give the impression of a struggling for equilibrium. Your own karmic energy swirls around in your energy field in the same way as the atmosphere here does, and this swirling sets the stage through which you can eventually neutralize karma.
Through Enochian Gemantria the letters TAN can be said to mean "justice," "equilibrium," and "fairness." The Guide of TAN is the Angel Madimi. The name MAD-I-MI breaks down to mean, "your own powerful god/goddess." Madimi is the feminine aspect of your Holy Guardian Angel, and it is Madimi's job to teach you to understand the purpose behind karma, specifically your own.
Karma is a natural law that acts on all planes below LIL. It seeks to bring "justice," "equilibrium," and "fairness" to the forces of duality. Any duality will create karma but specifically karma is produced when you block another person's unique path back to God. All the other so-called spiritual guidelines and rules are methods to teach you how to avoid blocking the path of another. The heavier your karma, the more you block the path of others, and the harder it will be for you to raise to the higher more rarefied Aethyrs.
Now TAN and its energies will begin to activate the forces in your life that can lighten your karma. Lighten is the key word here because karma can never be completely eliminated below LIL, but it can be lightened. This lightening is a two step process:
Your journey up the other Aethyrs will help you to accomplish this two step process, till you get to MAZ. In MAZ you shed the remainder of your shedable karma into the Cup of Karmic Residue. Then your karma will be light enough so that you can travel to most energy rarefied Aethyrs that lie above MAZ.
