Reading a lord placement
Two facts decide most of the reading: which house the lord rules, and which house it occupies. The first sets the subject, the second sets the arena. A 7th lord in the 10th makes partnership a career matter; the same 7th lord in the 12th sends it abroad or into seclusion.
- In its own house is the strongest placement a lord has — the house affairs rest on their own foundation.
- In a kendra (1, 4, 7, 10) the lord acts openly and visibly; in a trikona (5, 9) it acts with grace behind it.
- In a trik house (6, 8, 12) the affairs meet friction — though the 6th also gives the capacity to outlast opposition, and the 12th an inward or foreign turn.
Parivartana — when two lords swap
When the lord of house A sits in house B and the lord of house B sits in house A, the two houses are bound together. Either lord Dasha can then deliver both houses results at once, which makes an exchange one of the strongest single features a chart can carry.
Classically the exchange is graded by which houses are involved: between the favourable houses it is Maha, touching a dusthana it is Dainya, and involving the 3rd it is Khala. Note that this turns on the houses, not on kendra or trikona status alone — a 2nd-4th exchange is Maha even though the 2nd is neither.
One graha, two houses
Every graha except the Sun and Moon rules two signs, so most charts have five grahas each carrying two lordships. Both sets of affairs then surface wherever that graha sits, blended rather than kept apart — which is why the same placement can read as fortunate for one house and awkward for the other.
