The Tenth House and Where Income Comes From

You want to know what kind of work a chart is built for, or where someone's livelihood is most likely to come from. Brihat Jataka chapter 10 answers that question directly. It is one of the shortest chapters in the text, only four verses long, but it sets out the method that almost every later Vedic-astrology treatment of career builds on.

Two starting points

The chapter opens with a clean two-sentence rule. Verse 1 says wealth comes from the figure represented by the planet sitting in the 10th house from the lagna or from the Moon. The avocation itself, the kind of work the person actually does, comes from the planets that lord the navamsas occupied by the lords of the 10th from the lagna, the Moon, and the Sun BJ 10.1.

Two pieces are at work there: where the wealth comes from, and what the work itself is. They get read separately.

For the source of wealth, look at the 10th from your lagna and the 10th from your Moon. Any planet sitting in those houses points to the source. Sun is the father. Moon is the mother. Mars is an enemy. Mercury is a friend. Jupiter is a brother. Venus is the wife. Saturn is a servant.

The figures don't read literally as kinship in modern practice. Mercury in the 10th doesn't mean income comes from someone named Friend; it points to peer-level connections, intermediaries, communicative work. Venus in the 10th can mean income literally through a spouse, but it more often points to income colored by Venus's nature: pleasure goods, partnership-driven work, aesthetic skill. The figure names a relational type, and you read it for the kind of source it points to.

Why the 10th carries this weight

The 10th house, from Module 1 lesson 3, is the house of work in the world: career, public role, action that produces a result others can see. Brihat Jataka 1.15 lists it as the house of avocation in the canonical twelve-house list BJ 1.15. When chapter 10 turns to career, it begins from the 10th because that is where the chart locates the question.

The chapter goes further. Verse 1 also asks you to read the 10th from the Moon, since the Moon is the mind, and the mind's relationship to work matters as much as the chart's structural one.

Verse 1 then adds the navamsa layer. For the avocation itself, you read the planet that lords the navamsa occupied by the 10th lord. The same exercise applies from the Moon and the Sun. The navamsa is the chart's most important divisional reading, which Module 9 covers in detail. For now, treat it as the chart's second, finer-grained look at the same placements.

Try this

Find the 10th house from your lagna and the 10th house from your Moon. Note which planets, if any, sit in those houses. Then find the lord of the 10th from your lagna and check where it sits, and what sign's navamsa it occupies. The next lesson reads the navamsa lord and tells you what kind of work the chart points toward.
