Module 4 · Lesson 4-9 · 16 min
Somewhere in your chart, your mother has a career. Your spouse has a bank account. Your children have children. Not as metaphors — as houses, with signs, lords, and occupants, computable tonight from the one wheel you already own.
The rule is derived houses: to read a relative's life, treat their house as their lagna and count their twelve from it. Your 4th is your mother's 1st; her 2nd is your 5th; her 10th is your 1st. One chart — and everyone you know is hiding inside it, each carrying a full twelve-house chart of their own.
Last lesson counted the Nth from the Nth. This lesson sets the two numbers free: any house from any house, any person from any anchor. It is the final tool of Module 4 — the one that turns a chart of you into a chart of your whole world.
By the end: Rotate the wheel around any relative — mother's 4th, spouse's 7th, father's 9th — and compute any derived house on sight, reading their career, wealth, and family as secondary testimony beside the primary three-fold audit.
To read a relative's life, rotate the wheel: their house becomes their 1st, and their twelve houses count forward from it. You made this exact move in lesson 3.8, re-anchoring the chart to the Moon. Same maneuver, new anchor — one wheel, and it is everyone's wheel.
Your 4th is your mother's 1st. Her 2nd is your 5th, her 3rd is your 6th — her whole chart, folded into yours.
Mother: the 4th. Father: the 9th — this course's convention, flagged honestly when you first met the houses. Younger siblings: the 3rd. Elder siblings: the 11th. Children: the 5th. Spouse: the 7th. Pick the person, find their anchor, and the derivation starts there.
A question about your elder sister's marriage starts at your 11th — her lagna — never at your own 7th.
The Xth house from the Yth: start at Y, count it as one, step forward X houses, subtracting twelve on overshoot. Mother's career: the 10th from the 4th — count 4, 5, 6, on to the 1st. Spouse's career: the 10th from the 7th — your 4th.
Mother's wealth: the 2nd from the 4th — your 5th. Your creativity house is holding her bank account.
Spouse's wealth: the 2nd from the 7th — the 8th. This is the classical reason the 8th signifies inheritance, dowry, and in-law money: it is literally the marriage partner's bank account. Likewise the father's wealth — the 2nd from the 9th — lands on your 10th.
Spouse's siblings: the 3rd from the 7th — your 9th. The in-laws scatter across houses you thought you knew.
Set X equal to Y and derivation collapses into last lesson's rule. Grandchildren: the 5th from the 5th — the 9th. Your children's children live in your fortune house, and the Nth-from-the-Nth turns out to be one setting on a much larger machine.
The 9th from the 9th — your father's father — is the 5th. Grandfather and grandchildren trade houses across the 5-9 circuit.
The 8th is your transformation house and your spouse's wealth. The 6th is your service-and-disease house and your father's career. Both readings are true at once — layered meanings are why two astrologers can say different things about one house and both be right.
A strong 6th: hard service for you, a solid career for your father. One house, two honest sentences.
The one idea to keep
Twelve houses hold everyone: pick the person, rotate the wheel, read their twelve. But derived readings are secondary testimony — judge the relative's topic by primary house, lord, and karaka first, then refine with the derived chart. Arithmetic never replaces the three-fold method.
A client asks whether her mother's stalled career will recover. Which house in the client's own chart carries the mother's career?
Anchor first: the mother is the 4th. Then count her 10th from there, inclusively.
Open Priya's chart — Cancer lagna. Her spouse's career: which house of hers, and which sign?
The spouse anchors at the 7th. Count the 10th from it, then walk the signs from Cancer to name it.
Why does classical Jyotisha assign inheritance and in-law money to the 8th house?
Whose 2nd house is the 8th, counted by derivation?
A student takes a question about a client's father's career, jumps straight to the 6th house — the 10th from the 9th — and delivers a verdict. What did they skip?
Where does derived testimony rank in the method you built in lesson 4.7?

Five fresh derivations under the clock — pick the anchor, rotate the wheel, count clean, and keep the testimony in rank.
