Vulcan, a hypothetical planet once believed to exist inside the orbit of Mercury. Initially proposed as the cause for the perturbations in the orbit of Mercury, some astronomers spent many years searching for it, with many instances of people claiming to have found it.

In esoteric astrology one can look at Uranus as the higher octave of Vulcan (as well as Mercury) as once Vulcan has helped to destroy the attachments and adherence to the forms created by the lower self, Uranus can then work as the channel for the birthing of new.

That is why the Moon is spoken of in the ancient teaching as “veiling either Vulcan or Uranus.” This hint or inference has always been here and astrologers would do well to experiment with this suggestion I have made anent the Moon and (instead of working with the Moon) let them work with Vulcan when.


Esoteric Astrology, simply stated, is spiritual astrology. The focus ofEsoteric Astrology is less upon mundane material manifestations and outereffects, and more about soul evolution and spiritual causes. An important partof Esoteric Astrology is integrating astrology with the seven Rays, or theseven types of divine energy and universal motivation. Many EsotericAstrologers study the work of Alice A. Bailey, especially her 1951 book'Esoteric Astrology', which is part of her series of 24 books ofesoteric philosophy. The following quotes are relevant:

'Astrology is built upon the mystic and intimate connection betweenthe heavenly bodies and mankind and is one of the great secrets of Initiationand the occult mysteries.' - Secret Doctrine II, 525

'Astrolatry or the adoration of the Heavenly Host is the naturalresult of only half- revealed astrology.. Hence, divine Astrology for theInitiates; superstitious astrolatry for the profane.' - Secret DoctrineIII, 337

The program Astrolog supports Esoteric Astrology in addition to classicmundane astrology. The following is a description of the Esoteric Astrologyfeatures in Astrolog:

Esoteric Astrology Bodies

Esoteric Astrology charts often include additional bodies beyond what's presentin a mundane chart:
  • Vulcan: Astrolog can compute the position of Vulcan, and display itwith its downward pointing arrow glyph. Vulcan is a non-physical planet, whichmeans its physical location can't be scientifically proven yet. Astrolog usesthe L.H. Weston proposed ephemeris for Vulcan (the same as Solar Fire). Even ifVulcan isn't displayed in charts, it's useful to have defined as a planet foresoteric rulerships. Vulcan represents the forge, which anchors and purifiesboth physically and spiritually, hence its downward pointing arrow glyph.
  • Earth: Astrolog can include the position of Earth in standardcharts. In a geocentric chart, the position of Earth is its heliocentricposition, which means the Earth is always located opposite the Sun.
  • Pluto glyph: Astrolog can display Pluto using its esoteric glyph ofan upward pointing arrow, representing liberation from form. This option is inaddition to two other Pluto glyphs it supports: The standard circle overcrescent over cross commonly used in Western astrology, and the 'PL'glyph commonly used in scientific astronomy.

D.K. ayanamsa: Related to the positions of planets, Astrolog has asidereal astrology setting for the ayanamsa (zodiac degree offset) called the'Djwhal Khul' system, which is based on Master D.K.'s writings forthe date of the first decanate of the Age of Aquarius. Esoteric Astrologyprimarily uses the tropical zodiac, however it also includes a siderealayanamsa with a relation to Esoteric Astrology that some sidereal astrologersuse.

The following video demonstrates some Esoteric Astrology features ofAstrolog. It animates planetary orbits in 3D, including Vulcan. It features the'12 bodies' of Esoteric Astrology: Sun through Pluto, plus Vulcannext to the Sun and the Moon orbiting Earth. Positions are astronomicallyaccurate, although on a logarithmic scale from the Sun so the planets can beevenly distributed from it. Planets are colored according to their Ray, e.g.Indigo Ray 2 Sun, Green Ray 3 Earth, Yellow Ray 4 Moon, etc:

Esoteric Rulerships

Esoteric Astrology features alternate rulership sets for more spiritualconsiderations of planets. Beyond the mundane set of rulerships, there areesoteric rulers which operate on a soul or spiritual level, and Hierarchicalrulers which operate on a planetary or solar level. For example, the mundaneexoteric ruler of Aries is Mars, representing forceful and aggressive action.However, the esoteric ruler of Aries is Mercury, to represent the mental causeand design of that initiating energy. Finally, the Hierarchical ruler of Ariesis Uranus, to represent the growth and overall purpose of the influx ofinitiating energy in the first place.

Astrolog can list signs, list planets, and list Rays, showing how eachcomponent relates to the other two. What follows are three different tables,which display the same information, except that each is indexed by sign,planet, or Ray.

Below is a list of the 12 zodiac signs. Each sign is associated with 1 to 3Rays. Each sign's exoteric, esoteric, and Hierarchical ruler(s) are listed.Exoterically, some signs are ruled by two planets: A classic planet visible tothe naked eye, and an outer planet that was more recently discovered and whichonly plays a role when the personality is seeking personal growth. Esotericallyand Hierarchically, sometimes the Sun or Moon acts as a veil for deeperenergies.

Below is a list of the seven Rays. Each Ray has a name, and represents aparticular type of will. Each Ray is associated with three different signs, andone or two planets. Each Ray is associated with one sacred planet: When a Rayis associated with two planets, the first planet listed is the non-sacredplanet, and the second is the sacred planet.

The 'slice' value of a Ray is the number of signs associated withthat Ray, each proportioned by the number of other Rays also associated withthat sign. For example, Ray 5 is associated with Leo (along with Ray 1),Sagittarius (along with Rays 4 and 6), and Aquarius (only Ray 5). Therefore Ray5's slice value is 1/2 + 1/3 + 1.0 = 1.83. Notice how Ray 4 has the largestslice value, because it's the only Ray associated with both Taurus and Scorpio(getting 2.0 from those two signs) however it only has a 1/3 slice ofSagittarius (along with Ray 5 and Ray 6 which are also associated with it).

Ray Rulerships

A 'Ray rulership' is when a planet of a given Ray is positioned ina sign of the same Ray. For example, Sun (Ray 2 planet) in Gemini (Ray 2 sign)is a Ray rulership. Similarly, a 'Ray debilitation' is when a Ray Xplanet is opposite a Ray X sign. For example Moon (Ray 4 planet) in Gemini, asign which is opposite Sagittarius (a Ray 4 sign) is a Ray debilitation. Themeaning of a Ray rulership is a pure and undiluted influx of Ray energy,because both the Cosmic sign and the systemic planet are channeling the sameRay energy to our world.

Vulcan Astrology Glyph

Note that for all Rays except Ray 1, there exist opposite signs are boththe same Ray, so that Ray has only one possible Ray debilitation. For example,the three Ray 2 signs are Gemini, Virgo, and Pisces. That means there are threeRay rulership positionings for Ray 2, such as Ray 2 Jupiter in Gemini, Virgo,or Pisces. However since Virgo and Pisces are opposite each other, the only Ray2 debilitation is when a Ray 2 planet is in Sagittarius.

A 'house Ray rulership' is when a planet of a given Ray ispositioned in a house aligned with the same Ray. For example, Saturn (Ray 3planet) in the 7th house (Ray 3 house, because it corresponds to the 7th signLibra, a Ray 3 planet) is a house Ray rulership. The meaning of a house Rayrulership is similar to a Ray rulership, except the pure Ray energy ismanifesting in the world, because both the systemic planet and the personalityoriented house are bringing forth that Ray.

A 'double Ray rulership' is both a Ray rulership and a house Rayrulership at the same time. For example, Venus in Sagittarius and 11th house isa double Ray rulership because it's a Ray 5 planet in a Ray 5 sign and a Ray 5house. A double Ray rulership is very strong, because it's a pure and undilutedinflux of Ray energy that's also manifesting in the world.

Below is a table showing all Ray rulerships. Each Ray (and planets of that Ray) are on the vertical axis, and each sign/house is on the horizontal axis. If the planet in that sign is a Ray rulership it's indicated by a green 'RUL', and if a Ray debilitation then by a red 'deb'. Note the non-equal distribution, in that nearly half of all planets are Ray rulerships if in Capricorn or the 10th house, and nearly half of all planets are Ray debilitations if in Gemini or the 3rd house.

Esoteric Chart

Body Location Rulers House Rulers Power Rank Percent

Astrolog provides an esoteric chart which displays Esoteric Astrology andRay information for a given time. Display it with the 'Chart /Esoteric' menu command, or the -7 switch on the command line. An exampleis seen above, which is for this chart.

In the first section, this chart lists the planets, showing each planet'sRay, the planet's position and the Ray(s) of its zodiac sign, and rulershipinformation about the planet's zodiac position and house position. Thatincludes whether the planet exoterically rules or is debilitated in the sign(indicated with 'R' or 'd' characters), whether the planetesoterically rules or is debilitated in the sign ('S' or's' characters), whether the planet Hierarchically rules or isdebilitated in the sign ('H' or 'h' characters), whetherthe planet exalts or falls in the sign ('X' or 'f'characters), and finally whether the planet Ray rules or is Ray debilitated inthe sign i.e. whether the planet's Ray is the same as one of its sign's Rays('Y' or 'z' characters). For a 'double Rayrulership', or when a planet's Ray is the same as both the sign's andhouse's Ray, the 'Y' will be 'Y2' instead. Finally theoverall power of each planet is listed, based on its inherent strength,positioning, and aspects, which is computed in the same way as in Astrolog'sinfluence chart (accessed with the -j command switch).

Esoteric astrology chart

In the second section, the esoteric chart lists the seven Rays, showing thecount of planetary sign positionings that are associated with that Ray, thetotal power of those planets, and the rank of each Ray's total power and thepercentage covered by that Ray. This can be used to help see which Rays aremost influential in a chart. The same counts and powers are repeated, howeverthis time a sign associated with multiple Rays only contributes proportionalslices of power. By default, each Ray is associated with three signs, so forbalanced Ray coverage that gives each Ray an equal potential for power, thefirst 'count' values are preferred. However, some signs areassociated with one Ray, while others are with two or three, which meanscertain signs have triple potential to contribute power, so for balanced planetcoverage that gives each sign an equal potential for power, the second'slice' values are preferred.

To describe the last part above in more detail, the 'count' and'slice' values are two different ways to consider Ray influence:

  1. The 'count' value (shown in the left half of the Ray list above)is Ray focused, and treats each Ray equally. Any planet in a sign contributesits full power to each of the Rays associated with that sign. That is thesimplest approach, since it's balanced with respect to Rays, because each Rayis associated with exactly three signs. It means that each Ray has an equalchance to be the most or least powerful Ray, so for questions of 'whichRay is the most influential' in this type of analysis, the Ray focused'count' powers are recommended. However, it does mean certain signscontribute more power than others, e.g. a planet in Scorpio contributes onlyonce to just Ray 4, while a planet in Sagittarius contributes to Rays 4, 5, and6 (triple the amount).
  2. The 'slice' value (shown in the right half of the Ray list above)is planet focused, and treats each planet equally regardless of what sign it'sin. Any planet in a sign divides its power equally among each of the Raysassociated with that sign. This is balanced with respect to planets, becauseeach planet's total contribution to one or more Rays is the same regardless ofits sign. Note that the total of all 'slice' values is equal to thenumber of planets, and the total of all 'slice' Ray powers is equalto the total of all planet powers in the first part (planet list) of theesoteric chart. However, this does mean that certain Rays tend to getemphasized more than others, based on how often they have to share with otherRays of a sign. Ray 4 which has the highest inherent 'slice' value(because it's the sole Ray for both Taurus and Scorpio) tends to have thehighest power in the 'slice' part of an esoteric chart. For example,in my own chart above, Ray 4 has nearly twice the 'slice' power ofthe Ray in 2nd place.

Graphic Ray Chart

Astrolog features a graphical version of the esoteric chart described above,which graphs Ray influences over time. It's effectively an ephemeris of theseven Rays, mapping each of their powers over time. An example picture can beseen above, which shows the month of this chart. This is a 'count' based Ray centered graph (although'slice' based planet centered graphs, as well as graphs that coverjust one month instead of the entire year, can be done as well). Each Ray hasits own column, and each column is 600 power units wide (number customizablewith the -Y7 command switch), with 0 power on the left edge and 600 power onthe right.

Looking at the sample graph, some parts are readily apparent. Notice howRays 2 and 6 both have relatively high power from late August to lateSeptember, which is when the Sun (and Vulcan, Mercury, and Venus which arealways near it) are in Virgo (a Ray 2 and Ray 6 sign). Around the time the Sunenters Libra (a Ray 3 sign), the power of Ray 2 and Ray 6 drops, and Ray 3increases. Much longer and therefore more subtle Ray power cycles are dependentupon the movements of outer planets.

There's one more column for the average power of all seven Rays. The averageline is much smoother, because often when one Ray is being emphasized, otherRays are being ignored, which frequently averages out. However it's notperfectly smooth, because times of general intensity such as New and Full Moonsgive the planets themselves (and therefore the Rays they contribute to) extrapower. Also, Ray focused 'count' values may result in extra totalpower when many planets are in Sagittarius and Capricorn, because those signsare each associated with three Rays (e.g. notice the average line is slightlyhigher during December when the Sun and nearby planets are in those signs).


Astrolog can customize various settings associated with Esoteric Astrology:
  • Sign Rays: Change the Rays associated with signs, with the -Y7Ccommand switch. Each sign may be associated with multiple Rays. By default eachsign is associated with 1-3 Rays.
  • Planet Rays: Change the Ray associated with planets, with the -Y7Ocommand switch. Each planet is associated with one Ray. Planets may also beassociated with no Ray, e.g. the Rays associated with asteroids like Ceres areunknown, although one may optionally assign a Ray to it if they believe theyknow what it is.
  • Ray colors: Change the colors use to display Rays, with the -Yk7switch. Astrolog uses rose by default for Ray 6, however some applications likeSolar Fire uses light blue for it.
  • Esoteric rulerships: Assign the sign (or signs) that a planetesoterically rules, if any.
  • Hierarchical rulerships: Assign the sign (or signs) that a planetHierarchically rules, if any.
  • Esoteric Astrology influences: Assign power numbers. This includesthe bonus power given to a planet located in a sign it esoterically rules, aplanet in a sign it Hierarchically rules, and a planet in a sign it 'Rayrules' as described earlier. Also, bonus power can be defined for planetsin the house corresponding to the sign it esoterically, Hierarchically, and Rayrules.

Triple Sun Charts

Symbol of vulcan astrology

A Triple Sun chart is a special type of tri-wheel that some EsotericAstrologers make use of. For background information and details about TripleSun charts, see thisarticle by Stephen Pugh. All three wheels in a Triple Sun chart are variations ofthe natal chart, superimposed in a particular manner:

  1. Outer wheel - exoteric: The Sun is rotated to start of the Ascendant’ssign. (This is the same as a classic solar chart.) This wheel shows the birthSun, and represents the personality. It's associated with activity andobjective appearance.
  2. Middle wheel - esoteric: The Ascendant is rotated to start of itsown sign. (This is closest to a standard chart, in that planets are neverrotated over 30 degrees.) This wheel shows the rising Sun, and represents thesoul. It's aligned with love-wisdom and subjective quality.
  3. Inner wheel - Hierarchical: The Earth is rotated to start of theAscendant’s sign. (Note planet positions here are always 180 degrees oppositethe exoteric wheel.) This wheel shows the opposite Sun, and represents theMonad. It reflects will and divine life.

Note it's important to remember that a Triple Sun “chart” is not thesame as a Triple Sun “Horoscope”. The chart is just some objectivelycomputed and drawn graphics, however the true Horoscope involves spiritualpractices and meditations to properly use the chart. Below are some quotationswhich inspire superimposed charts:

“When the Sun sign, with the exoteric rulers, is worked out in a chart,the rising sign with the esoteric rulers is also worked out and the two aresuperimposed upon each other, the problem of the disciple in any oneincarnation will appear.” (Esoteric Astrology p514)

Why do people believe in astrological compatibility. “The Sun sign, governed by the ruling esoteric planets and the risingsign governed also by the esoteric planets, can both be used in casting thehoroscope of the initiate; when superimposed upon each other, the outer life ofthe initiate in the three worlds and the inner life of subjective realizationwill appear. This mode of super-imposition will be a feature of the newastrology.” (Esoteric Astrology p514)

'I would call you attention to the fact that in any one incarnationthe Monad works through the Opposing Sign, the Soul through the Rising Sign andthe personality through the Sun Sign, and these necessarily vary from life tolife.' (Unpublished Zodiacal Meditations, 1943)

Astrolog can display Triple Sun charts. It doesn't have a direct or simplemenu command to display them, however one can configure the program toautomatically compose them given any natal chart. To do that, select atri-wheel, and set the Whole house system. Load the natal chart into all threewheels, and configure the three wheels individually to rotate the planetsappropriately. This can be done with the following command line. In the Windowsversion, first load or enter in your natal chart data, and then copy/paste thetext below into the 'Edit / Enter Command Line' menu command toswitch to a Triple Sun chart of your natal data:
