01Overview
02What sits at the bottom of a chart
The fourth house is the private half of everything: the house you actually live in, the land under it, the schooling that formed you, and the quality of rest available when nobody is watching. It is a kendra, so it is structurally strong, and it is also the point in the chart furthest from public view. Surya, whose entire nature is to be seen, is an unusual tenant for a department defined by not being on display.
03What this placement is credited with
04The lagna that turns this into a strength
Directional strength is genuinely against this placement, since Surya's digbala belongs to the tenth house and the fourth is the point diametrically opposite it. What that argument leaves out is dignity: a Taurus lagna puts Leo in the fourth, so Surya is the fourth lord standing in its own sign, one of the steadiest ordinary configurations a house lord can hold. A Capricorn lagna puts Aries there and the Sun is exalted at the base of the chart, which no directional argument cancels.
05Two households under one house number
| A base that holds | A base that is defended | |
|---|---|---|
| The 4th sign | Aries (exalted) or Leo (own sign) | Libra (debilitated) — a Cancer lagna |
| The 4th lord | Strong and outside the dusthanas | Weak, burnt, or in the 6th, 8th or 12th |
| The Moon's condition | Well placed and clear of the Sun | Close to the Sun, or afflicted elsewhere |
| Benefic contact | Jupiter or Venus reaching the house | None, or malefic contact only |
| What ease depends on | Nothing in particular — it is simply available | Position, order, and things being arranged correctly |
06Whether the Moon can be burnt at all
Most tables of combustion give Chandra an orb of about twelve degrees, which would make the Moon combust for roughly two days either side of the new moon in a great many charts. A substantial body of practice refuses that reading and treats solar closeness for the Moon as amavasya weakness — a question of waning light and paksha bala — rather than astangata, on the grounds that the Moon's brightness is borrowed from the Sun to begin with and so cannot be overwhelmed in the same sense. The two positions produce different judgements about the same degrees, and neither has displaced the other.
