Combustion, Cazimi & Under the Beams

The Sun gives life to the chart — but up close it overwhelms. A planet sitting too near the Sun is burnt: its own light is drowned out, its significations hidden or consumed by the Sun’s glare. This is combustion, and it is one of the heavier afflictions a planet can carry. Yet the rule has a startling twist at its very centre: move close enough and the burning flips into the single strongest placement of all. Distance from the Sun cuts three ways.

The Three Zones

Cazimi — within 0°17′ of exact. “In the heart of the Sun.” Far from being burnt, the planet is enthroned beside the king — its significations elevated and protected. One of the most powerful placements there is.

Combust — 0°17′ – 8°30′. Too close; the Sun overpowers the planet’s light. Its significations go hidden, consumed, or overruled. Like an official who serves directly under the king’s eye — one wrong move and the head rolls.

Under the beams — 8°30′ – 17°. Still inside the Sun’s glare but no longer burnt; the planet keeps most of its strength. An official at court, but not under constant watch.

Why Closeness Both Destroys and Crowns

The old image is the king and his court, and it explains the reversal cleanly. To stand near the king is dangerous: your own voice is lost in his, and serving directly under his eye, a single misstep is fatal — that is combustion. To stand at a courtier’s distance is safer, your light dimmed but intact — under the beams. But to sit in the king’s own heart, closer than anyone, is not danger at all: it is to be the favourite, raised above the whole court. That is cazimi. The same closeness that ruins at 5° exalts at ten minutes of arc.

Which Planets Get Burnt

Any planet conjunct the Sun can be combust, but two are caught far more often than the rest: Mercury and Venus never travel far from the Sun — Mercury stays within about 28°, Venus within about 48° — so they spend a large share of all charts under the beams or combust. A combust Mercury or Venus is common enough that it is worth knowing on sight rather than treating as a rare catastrophe. Cazimi, by contrast, is rare and precious: the conjunction has to be nearly exact.

How to Read a Combust Planet

Combustion tends to hide what the planet governs, or fuse it so tightly with the Sun’s themes — identity, ego, the self — that it can’t act on its own terms. A combust Mercury can struggle to separate thinking from self-image: the mind and the “I” run together, and an opinion feels like a person rather than an idea. A combust Venus can lose its own taste inside the need to be someone, love and worth pulled into the orbit of identity. The significations don’t vanish — they go underground, overruled by the Sun. Cazimi does the opposite: it lifts the same significations into clarity and power, the planet doing its finest work because it is one with the light rather than drowned by it.

As always, this is one testimony among many — read it inside the full strength-and-affliction picture, never as a lone verdict. A combust planet that is also dignified and received behaves very differently from a combust planet that is debilitated and unsupported.

A Note on the Degrees

The exact figures above are one common set; traditions differ. Some authors give cazimi as the Sun’s heart at a tight 0°17′, others allow a slightly wider margin or even measure it by the Sun’s body rather than by degrees, and the combustion and under-the-beams bounds vary a little from text to text. The principle is firm even where the minutes wobble: dead-centre is supreme, very close is ruinous, and close-but-not-touching is merely dimmed. The whole question of where one tradition draws a line that another draws elsewhere is part of the wider difference between modern and classical practice.
