Hey, what you described actually lines up almost word for word with how the Clergy describes what too much air does to a person, so your self-diagnosis is probably right on. On the
Invoking Air page High Priest Zevios Metathronos writes that air is "pure intellect" and that it "lacks feeling and emotion," and that an imbalance of too much air "makes one scatterbrained, high-strung, and causes nervous exhaustion." The "soul saturated in air" you felt in meditation is the same thing the page is talking about. So is the flatness. Air people, as the Clergy describes them, can have an overactive mind and live in their head, which is exactly the place where feeling stops arriving.
To your real question, and the short answer is that
invoking earth alone is generally not the whole answer if you have years of accumulated air. The principle the Clergy lays out on the
Invoking the Elements page is the one to lean on here: "Fire is opposite Water and Air is opposite Earth. The opposite element is what is needed to fix the imbalance." It also adds a very important note, that "invoking the lacking element can create a temporary backlash in the over-dominant element." That is the Clergy's own way of saying that when you start feeding earth into a system that is full of air, the air will surface and move, and you have to be ready for that. So both sides of the work are real, and both come from the public teaching, not from anything I am improvising.
The mechanism for it is also already on the site, and it is what answers your "do I have to breathe the air out too" question without me inventing a custom protocol. On the
Concentrating the Elements page the Clergy shows the inhale-and-exhale mechanic directly: "Breathe in the element of fire, and upon the exhale, direct all of it to your base chakra, so it is concentrated." That same inhale-element, exhale-direct-to-a-chakra pattern is how you would both build earth into your base chakra and direct the built-up air out of
the throat chakra where it lives. The Foundation Meditation page lays out the underlying model: inhale to absorb with the whole body like a dry sponge, exhale to push out, and the explicit warning that "exhaling energy is for specific purposes and shouldn't be done regularly." That is the Clergy's own caution that the exhale side of elemental work is not a casual daily thing, it is a deliberate advanced practice.
On the natal chart piece, an air ascendant and almost no earth does make balance work more important for you, not because your chart is a life sentence, but because the Clergy treats the natal chart as a map of the soul that informs practice. You can actually see that framing in how the High Priest answered a member who came in with 0% earth in their chart in
this forum reply, telling them to use creativity and to learn maintenance rather than treating the deficiency as fate. Air-heavy nativities are also exactly the people the High Priestess has in mind in her
Regrounding After Meditation post, where she notes that those who are more Vata, which she frames as Air dominant, may want to do the palm-friction regrounding for a longer period than other constitutional types. That is a named-author Clergy instruction written specifically for someone with your constitution, and it is the gentlest, most immediately useful thing on your list. Pair it with her
Grounding; Strengthening Muladhara Chakra sermon for the longer-term earth-side work on the root chakra itself, since
the base chakra is the earth chakra per the
Base Chakra page.
A sensible order to actually read and practice, as written, would be this. Start with
Invoking Air to confirm in the Clergy's own words what you are feeling, then
Invoking Earth for the earth-side method, followed exactly as written.
Concentrating the Elements next, for the breath-direction mechanic, and
Circulating the Elements for the larger alchemical framework that explains why just adding earth is not the full picture when there is real saturation. For immediate, gentle practice, do High Priestess Lydia Coventina's
Regrounding After Meditation protocol after every meditation, and read her
Grounding; Strengthening Muladhara Chakra for the longer-term earth-building work. The
Foundation Meditation page is also worth sitting with because it is the basis for all breathwork in this system.
One important guardrail, because this is real advanced work and not something to freestyle. Both
Invoking Air and
Invoking Earth carry the same explicit cap from the Clergy: "Do this for seven breaths, AND ONLY SEVEN BREATHS! DO NOT DO ANY MORE! YOU CAN EVEN DO AS LITTLE AS 2-3 BREATHS, BUT NO MORE THAN SEVEN!" That cap is there for a reason, and a member who has self-diagnosed this strongly should not invent a longer or harder version of either practice. The
Invoking the Elements page also lists real contraindications for elemental work, and is worth reading for that reason before you start. The Clergy's framing throughout is that elemental work is among the highest forms of magick, and that doing it well is more important than doing it fast. The High Priest's own framing of
planetary squares is also worth reading for your own situation, since the air-sign squares you mentioned are a real contributing factor and the Clergy has already addressed that question in their own words.
The honest take on this, and credit to the Temple of Zeus Clergy for preserving this body of work in the first place, is that you are not looking at a one-week fix. You are looking at the kind of rebalancing the Clergy describes as ongoing maintenance, the same way the High Priest told the member with 0% earth in
that same reply that maintenance was going to be the biggest learning curve. Start gentle, with the regrounding and the earth-invocation as written, build slowly, and let the air-release side be something you approach through the concentrating and circulating pages rather than something you improvise. Tracking your own responses in your own way between sessions is also a real help, since it lets you see your own progress more honestly than guessing.
Hail Zeus, and good luck with the work.
