Combust planets: how close is close, and why the answer depends on who you ask

Whether a planet in your chart counts as combust can change on the authority you follow — by a factor of more than two.

The version of this page that stood here from November 2022 carried a promise in its title that the article itself did not keep. It said combust planets gift you unexpected rewards, and then explained that a combust planet loses potency and cannot deliver what it promised in the chart.

Both of those are defensible positions. They are not the same position, and a reader is entitled to know which one the page is taking.

This rewrite takes the second, states it plainly, and then deals properly with the condition that would make the first one true. It also fixes a piece of physics, and adds the thing the original most needed — a statement of where the degree limits come from, and what happens if you use a different set.

What combustion is

Asta, or moūḍhya — a planet close enough to the Sun in longitude that, in the plainest version of the idea, it would be lost in the glare if you went outside and looked.

The 2022 version used the analogy of degrees of burn, and that is the right analogy. It is worth following it further than the page did, because the whole argument turns on it.

One correction to the physics while we are here. The earlier version said Mercury is combust most often because, as the smallest planet, it is closest to the Sun. Size has nothing to do with it. Mercury is combust most often because it orbits inside the Earth and never appears more than about twenty-eight degrees from the Sun in our sky — it simply has nowhere else to be.

The degrees, and where they come from

Here is the table the 2022 version gave, which is the set I work with.

And here is the thing the earlier version left out, which matters more than any single figure in it.

These are not the only limits in use, and the differences are not small. The values commonly cited from Parāśara run considerably wider — fourteen degrees for direct Mercury against five or six, seventeen for Mars against seven or eight, fifteen for Śani against nine or ten. A planet at twelve degrees from the Sun is combust on one reckoning and perfectly clear on the other.

That is not a quibble. Run both sets against eighty years of actual planetary positions and the difference shows up as the proportion of people who have the condition at all.

Look at Maṅgala. One set of limits says roughly one person in fifteen has a combust Mars. The other says one in six or seven. More than twice as many people, for the same sky, on a difference of opinion about where the glare ends.

So the rule that comes out of this is simple and nobody follows it. State which limits you are using. A reading that says “your Mars is combust” without saying at what orb has told you less than it appears to, because the reader cannot check it and a second astrologer may disagree for a reason that has nothing to do with the chart.

The figures above are the tighter set against the wider one, counted over 1950 to 2030. The Moon is separate and simpler: at twelve degrees either side it is within range for about one day in fifteen, which works out at roughly two days of every lunar month.

It is not a yes or a no

This is where the burn analogy earns its place, and where most writing on the subject goes wrong.

Combustion is treated in practice as a switch — the planet is combust or it is not, and if it is, it is written off. The classical description does not support that and neither does the analogy the 2022 page reached for. A planet at the outer edge of the orb and a planet sitting on the Sun’s exact degree are in conditions that have almost nothing in common.

Four things change how much it matters, and the earlier version listed them correctly.

→  How close it actually is, which is the main one and the one usually left unstated

→  Whether the sign is friendly, and whether the graha is exalted or debilitated there

→  Whether it is alone with the Sun or in company

→  How strong the Sun itself is — a weak Sun burns less

Which means the useful question is never “is it combust”. It is “how many degrees”, and that number should appear in any reading that raises the subject at all.

And then there is the heart of the Sun

Now the condition that would make the original headline literally true, and which the 2022 version did not mention.

Carry the burn analogy all the way to its end. As a planet comes closer to the Sun it is more and more overwhelmed — and then, at the very last, it is no longer beside the fire. It is inside it.

The Western tradition has a precise name and a precise orb for this: cazimi, from the Arabic for “in the heart”, taken as within about seventeen minutes of arc — roughly a third of a degree. A planet that close is not held to be burnt. It is held to be enthroned, sitting with the king rather than standing in his glare.

It is rare, and it is worth knowing how rare.

Rare, but not so rare that you will never meet one. In a practice of any size you will see a handful, and the distinction between that chart and a chart with a planet at eight degrees from the Sun is the difference between the two readings this page has been arguing about.

A note on where that idea comes from. The seventeen-minute orb and the name cazimi belong to the Hellenistic and Perso-Arabic tradition rather than to the Sanskrit texts. I am setting it out because the arithmetic is the same sky and because it is the only version of “combustion brings rewards” I can state precisely. Whether the Indian tradition recognises an equivalent, and at what orb, is a question for a teacher rather than a blog post, and I will not pretend to settle it here.

What “reward” honestly means on this page

Setting the heart of the Sun aside, the 2022 version had a real teaching in it and it is worth keeping rather than dressing up.

The classical reading of a combust graha is a significations that cannot be displayed. The thing is there and it does not show. Whatever that planet governs in the chart tends to operate without visible credit, and the person carries it without being seen to.

The earlier page called this effacement, and said it leads to humility and to seeing past yourself. That is a devotional reading rather than a material one, and it is the honest version of the headline’s promise.

What it is not is a windfall. A page that tells someone their combust Śukra will produce unexpected rewards has made a claim that can be checked and will usually fail. A page that says the matters of that graha are likely to run quietly and without recognition has said something a reader can measure against his own life, which is a different and more useful kind of claim.

The remedial practice

The earlier version recommended the Pañcākṣarī mantra, or Rudrābhiṣeka. That stays, with the condition this practice applies to everything of the kind.

A remedy without a test attached is devotion, not a correction — and there is nothing wrong with devotion, provided it is named as such. If you take up a practice for a combust graha, decide in advance what would count as it having worked and over what period, and write it down before you start. If you cannot answer that question, the practice may still be worth doing, but it is worth doing for its own sake rather than as a repair to a chart.

That is the same standard applied everywhere else on this site and there is no reason for this page to be an exception.

The companion to this page

Worth reading alongside, because the two describe one phenomenon from two sides.

Mercury turns retrograde as it passes between the Earth and the Sun. That is the same event as its closest approach in longitude, which is why a retrograde Mercury is combust about sixty-one per cent of the time — computed on the twelve-degree retrograde limit in the table above.

Which means most of what is written about retrograde Mercury is describing combustion. Retrogression is a strengthening condition in the ṣaḍbala scheme. Combustion is a weakening one. They arrive together more often than not, and a reading that does not separate them will attribute the difficulty to the wrong cause every time.

What this page will not tell you

Four limits.

→  It cannot tell you whether a combust graha in your chart matters, without the degrees and the rest of the chart

→  It does not settle which set of limits is correct. It tells you the choice matters and that your astrologer should name his

→  It makes no claim that combustion produces material rewards, and the earlier version of this page should not be read as making one

→  It does not establish an Indian equivalent to cazimi. That is stated as a Western doctrine and marked as one

The second is the one to take away. There is no authority that settles the orbs, and anyone who tells you there is has not looked.

Where to start

Three steps.

→  Find the exact separation in degrees between the graha and the Sun. Not whether it is combust — how far

→  Check that number against the limits your astrologer uses, and ask him which set they are

→  If it is inside about a third of a degree, you are looking at something else entirely, and it is worth asking about

One number, and almost nobody looks it up. The difference between a graha eleven degrees from the Sun and one eleven minutes from it is the difference between a footnote and the most unusual thing in the chart — and both of them get called combust.
