Once a person is attuned and working with the 12D Shield daily, the Lightbody becomes aligned to the 12D Ray and this starts to build the spiritual foundation for the Soul, Monad and Avatar bodies. See Ascension Stages and the ES Core Triad.
At a certain level of proficiency, one can utilize the 12D Shield as a Transit Gate Vortex, or a Shadow Gate. This is a vortex set up specifically to exit out and clear low vibration energies, entities, and negativity from the space one has commanded with the 12D shield as GSF in the boundary test. We call that Commanding Personal Space with a boundary test using the GSF triad, which is the Threefold Founder Flame. This means one is stating that one chooses the consent and authority of God-Sovereign-Free, which is aligned to the Law of One, therefore the Christ authority.
In many of our community processes we teach an array of potential spiritual housekeeping or clearing techniques which can be acquired and learned through the many meditations. The Shadow Gate or Transit Gate Vortex is a basic technique that everyone will get a lot of benefit from. To clear out lower frequencies, misplaced entities, misqualified or negative energies that accumulate in a room, space and group aura field exposed to higher frequencies.
When in situations or locations of severe negative energy build up in the collective, the land itself, the buildings or structures, or interacting with a possessed person/group, these tools can be a lifesaver, and reduce psychic sponging or the toxicity from entering your field. One may also find that dedicating the meditation you are guided to may be dedicated to the specific area or energetic problem lightens the density. Sometimes we may feel too tired and can access a meditation on cell phone or other devices ( turn off wireless and place on airplane mode), to help clear the present space we may find ourselves.
Here are some basic spiritual housekeeping tools to explore and experiment with. Everyone is unique and must learn what works the best for them in a variety of circumstances. Remember that we do not impose our will on anybody or anything, however, we have a divine right to exist in the spaces without being attacked, parasitized and vampirized, and so we must strengthen our field awareness and our sphere of influence in the space. Here are some tools to be aware of not superimposing one's will to commit potential harm to others, but to access the natural laws to neutralize polarities or resolve the energetic conflict in the circumstance or space. These can be said out loud or said in the inner mind or imagined.
