Introduction
As I have stated in other twin papers, twin births are especially useful to this astrology. Why? Parents of twins usually know before birth they are having twins, so they pay especial attention to birth time. They do so because later those time differences are a conversation piece as well as forming part of the identity of the twins. So, birth time for twins is likely correct to the minute and the charts cast from them are also close to exact. Comparisons made between them are then based on correct astrology. That means twin births are especially good for testing a major principle of this astrological method, that planets on (≤2° orb) Angles are of primary importance in describing all our lives.

When one twin has a different sign on an Angle, their births are also useful for demonstrating the principle that astrological sets (aspects) ruling an Angle are of far more importance than those which do not.

Examples of this are shown in the samples below and in all of the twin papers on this site.

In this short paper, using astrology, we are going to identify the significant difference between the twin born healthy and the one born with myasthenia gravis. Two charts, the 1st and the 6th, are involved. Born four minutes apart, the twins are both female. The first-born twin was healthy, while the second-born one had myasthenia gravis.

All the biographical data on twins has been slim.

For twin No. 1 (#5604), the healthy twin, Astrodatabank had: American first-born twin born healthy.

For twin No. 2 (#5605), the one with myasthenia gravis, Astrodatabank had: American second-born twin born with myasthenia gravis.

I have written other papers on twins with the goal of identifying the differences in their astrology which accounted for the differences in their experienecs. Below are links to each of them:

The following discussion of myasthenia gravis and its causes comes from www.lifescript.com:
[Definition] Myasthenia gravis (MG) is a neuromuscular disorder that affects the junction between nerves and muscles. Its symptoms may grow progressively more severe over time. This is a potentially serious condition that requires care from your doctor. If you suspect you have this condition, contact your doctor immediately.

The thymus is an organ behind the breastbone, and it is thought to play a role in causing some cases of myasthenia gravis. Immune proteins called antibodies are produced by the thymus. In MG, some of these antibodies may target the acetylcholine receptors. It is still not clear why the thymus begins to produce these harmful antibodies.

That’s enough for our purposes. It states that myasthenia gravis may be a problem involving the individual’s immune system.

This is the only chart I have on myasthenia gravis. Naturally, I cannot even aim at establishing significators for this disease with one chart.

I have, however, looked at a number of immune system problems. They always involve mars and neptune forefront in the 1st and/or 6th chart. When saturn joins them, the condition becomes much more severe. If we include cancer as an immune problem, we can add the 7th chart. In fact, cancer of the sex organs also shows up in the 5th chart.

But for this disease, we are only differentiating the twin who has it from the twin who does not. For the disease, we are looking for a forefront mars/neptune set in the 1st and/or 6th chart. The set may also include saturn.

Since their 7th charts also include a forefront mars/neptune set, that chart is also shown below.

Below I have given a short summary of the areas of life covered by the three charts to be presented :

The 1st chart is a chart which describes the identity we formed in childhood and some of its somatic consequences—allergies and asthma, for two examples.

The 6th chart, like the 6th house, is correlated with health and service.

The 7th chart, the main chart of this method, contains a great deal of information about our lives. Theoretically, it is concerned only with matters pertaining to the 7th house, such as our relations with significant others, including marriage and business partners and close friends. However, it, too, contains information about health.

Before looking at the charts, I want to make available information about this astrological method:

This astrology uses the sidereal positions of the planets based on the Fagan-Bradley’s SVP.

Harmonics are taken from the sidereal position of the planets. The Egyptian harmonic, discussed in the paper “About This Method” (see Home Page), is used.

”Lights” include suns, moons, and moons nodes.

This method uses only conjunctions, applying and separating squares, and oppositions. Orbs for planets with lights is 5°; without lights, about 2.5°. Orb for MC/planet or Asc/planet is 2°. Planets so related to each other are referred to as in the same “set.” A set, then, is two or more planets (or an Angle) connected to each other through conjunction, square, and opposition within the defined orbs. The set is more active if it contains a light, and less active without one. Learning to look in terms of “crosses” can be helpful in rapidly finding planets that are in the same set.

Because this approach uses both a birth and conception chart and they share the same axis, birth houses usually overlap different houses of the conception chart. These are called “house overlaps.” House overlaps play an important part in this astrology as investigation of the charts below (and in other papers) will show. Throughout this paper I use the convention when writing about house overlaps of putting the birth house first, then the conception house. So, for instance, a “5th/1st” overlap refers to an overlap of birth 5th house with conception 1st house in that order.

Birth planets (including their harmonics) rule only birth houses. Conception planets (including their harmonics) rule only conception houses.

For a more thorough explanation of this astrological approach, refer to this site’s papers entitled “About This Method” as well as the one entitled "Chart Reading Rules." There is also a link to the method paper at the bottom of every paper.

About This Method

Chart Reading Rules

In the partial charts shown below, birth planets and their harmonics are inside the circle. Conception planets and their harmonics are outside the circle. Conception sidereal planets are red; conception harmonic ones, black. Birth sidereal planets are blue; birth harmonic ones, green. Occasionally, because of space limitations, I have had to violate this inside/outside arrangement, but the color coding remain constant.

Abbreviations used are b = birth, c = conception, and t = transiting. Even though the harmonic used for each chart is always two more than the chart’s number, in these papers I write the harmonic number the same as the chart number. For example, the 5th chart uses the 7th harmonic, but I have established the convention of writing harmonic planets for the 5th chart as, e.g., c5 mars, which reads, “the harmonic for the 5th chart for conception mars.

Now we can look at those charts.

Since the main difference between them occurs with their Angles, below each time I present only the partial chart for twin No. 2, the one born with myasthenia gravis, with the position of his Angles shown in the partial chart. Below the chart are his other house cusps. Below that, are the Angles and house cusps for Twin No. 1.

It is easy to see that the significant difference between the Angles of the twins occurs with the position of birth Midheaven. While Twin No. 2 (with myasthenia gravis) has B MC at 0 Virgo 39, ruled by mercury, Twin No. 1 has his B MC at 29 Leo 33, ruled by the sun.

Here is their 1st chart:

Placidus, Twin No. 1 (healthy): C MC—8 Cancer 03, c11—11 Leo, c12—10Vir, C Asc—4 Libra 53, c2—3Sco, c3—5Sag B MC—29 Leo 33, b11—30Vir, b12—25Lib, B Asc—16 Scorpio 08, b2—18Sag, b3—24Cap

Set (1) shows sun/mars/saturn/neptune with influence to B Asc and b 6th house through b mars. It also influences c 6th house through c1 neptune.

I like best the use of b mars, and omitting c1 mars. But, both can be included, because the light for this set is c sun, which is between the two mars. The “midpoint” between them is 2° 45’ cardinal. If I was going to include c1 mars, I should have put in c venus, which is at 28 Sagittarius 34. It rules C Asc and c 7th house.

Including all the planets, then, Set (1) influences two Angles and both 6th houses. It is certainly strong enough to cause health problems. Light/mars/saturn/neptune/6th is some kind of harsh (siege for mars/saturn/neptune) health condition.

Set (1) however, is the same in both twin’s charts. That is, it works equally in both charts. This afflicted 1st chart set may be part of the significator for myasthenia gravis, but it is not enough by itself to cause the disease. If it were, both twins would have been born with the disease.

When I write part of the significator, I am referring to the fact that significators for a condition may involve more than one chart.

Let’s see what is in their 6th chart.

Placidus, Twin No. 1 (healthy): C MC—8 Cancer 03, c11—11 Leo, c12—10Vir, C Asc—4 Libra 53, c2—3Sco, c3—5Sag B MC—29 Leo 33, b11—30Vir, b12—25Lib, B Asc—16 Scorpio 08, b2—18Sag, b3—24Cap

Set (2) contains mercury/mercury/mars/mars/saturn//neptune/neptune. That is interesting. Either it contains no light, or one of the mercury’s is acting as the light.

That is exactly what is happening. B6 mercury rules B MC for Twin No. 2, the one with myasthenia gravis. When mercury rules an Angle, it acts like a light and assumes the same orb as is given to lights—5°.

Twin No. 2, therefore, has light/mars/saturn/neptune influencing:

• B Asc and b 6th house through b mars.
• C 6th house through c6 neptune
• And, B MC through b6 mercury.

But, Twin No. 1, the healthy one, does not have b mercury ruling B MC, because his B MC is in Leo, ruled by the sun, which is not part of this set.

Just looking at it, it would still seem that Twin No. 1 also has a forefront light/mars/saturn/neptune influencing at least one Angle (B Asc) and both 6th houses. But Twin No. 1 does not have a light in the set! In his chart, b mercury does not rule B MC, which is in Leo. Since he does not have mercury ruling an Angle, (and since b6 mercury in the set was the only light in the set for Twin No. 2), then Twin No. (1)'s set, even though it influences an Angle (B Asc), lacks a light!

Had those planets all been on an Angle, we would not have needed the light to “activate” the set. But they were not. They were in a set influencing at least one Angle. And that set for Twin No 2, the ill one, included a light, whereas the one for Twin No. 1, the healthy one, it did not. A set which influences an Angle, rather than is on it, must include a light in order to be forefront in the life. Our lights give birth to the type of consciousness represented by our planets.

This is the set, and this the chart (at least so far) which differentiates the life of the one twin from that of the other with respect to their health differences.

What’s in their 7th charts?.

Placidus, Twin No. 1 (healthy): C MC—8 Cancer 03, c11—11 Leo, c12—10Vir, C Asc—4 Libra 53, c2—3Sco, c3—5Sag B MC—29 Leo 33, b11—30Vir, b12—25Lib, B Asc—16 Scorpio 08, b2—18Sag, b3—24Cap

Set (3) shows moon/moon/mars/neptune/neptune. It does not contain saturn, but from the beginning we hypothesized that the damaging set might not have to contain saturn. Mars/neptune is enough to show various immune responses.

Set (3) influences c 6th house through c neptune. It influences C MC through c7 moon. Therefore, this set is forefront and important in this chart.

Set (3), however, is the same in both twins charts. The biggest difference, after their Angles, is between their harmonic moons. Twin No. 1 has b7 moon at 24 Libra 14, while Twin No. Two has it at 23 Libra 32. Twin No. 1 has c7 moon at 23 Cancer 54, while Twin No. 2 has it at 24 Cancer 15. In this set, those differences make no difference in the validity of the set for each twin. Both have an active and valid Set (3).

Set (3) may be part of the total significator for myasthenia gravis, but by itself it does not create the condition.

Conclusion
We were able astrologically to separate these twins born four minutes apart with regard to the significators for the disease myasthenia gravis.

In the 6th chart showing health conditions, the twin with the disease had an active, forefront set containing light/mars/saturn/neptune with 6th house influence. The twin without the disease lacked a light for this set, and therefore, it was not active. These important differences stemmed from the slight differences in their birth Midheavens, which were only 1° 06’ apart, but they were in different signs, with different rulers. And only the ill twin's set contained the ruler which either was a light or acted like a light, mercury. While the healthy twin's set contained mercury, it did not rule an Angle, and therefore did not act like a light. And while his B MC was ruled by a light (b sun), b sun was not in the set.

The first time I concluded, through research, that mercury acted like a light (with a 5° orb) when ruling an Angle (and only then) was in investigating the death of Prime Minister Winston Churchill. He has two Angles ruled by mercury. Progressions of the malefics mars and saturn to them were instrumental in symbolizing his death. The only way a set not on an Angle can come forefront, as happens with mars and saturn for death, is if the set contains: (a) a ruler of an Angle, (b) a light that energizes the set, and (c) the mars or saturn. That discovery through use of Churchill's chart occurred many years ago and has held up since them. This twin study is a dramatic example of the fact that mercury acts like a light when it rules one (or more) Angles.

We cannot conclude anything about the other charts. The 1st and 7th charts may play a part in the total astrological identification of myasthenia gravis. It could also be true that only the 6th chart contained the significators. All we know right now is that only the 6th chart was significantly different for each twin.

Discussion
In this brief and short study I did not try to pin down the exact path played by the houses in these charts. I was only interested in whether or not each time the path included the 6th house, which it did in all three charts.

Is what has been seen here really the significator for myasthenia gravis? Maybe not. It may only be a significator for a class of diseases which have faulty immune response as an intricate part of the problem.

It may be a long time before complete (without any reservation whatsoever) significators can known, and when one immune disease can be differentiated from another, if that is possible. For all I know, there are many more things in these charts, both by inclusion and omission, which constitute “being part of the significator.”

Results obtained so far from twin studies show that just a tiny change in the astrology, like that shown for these twins, can radically alter the manifestation of a condition. Or, as happened with the second set of normal/retarded twins, another relatively small change can result in the “retardation” of the normal twin being “overruled,” or canceled.
