The angles are the 1st, 4th, 7th and 10th houses from the lagna. When a natural benefic rules an angle, the books say it gives up some of its good. When a natural malefic rules one, it gives up some of its harm. This blemish is called kendradhipati dosha. It is strongest for Venus, then Jupiter, Mercury and the Moon. The lagna lord is spared.
☕ An angle pulls toward the middle
'Kendra' means an angle. 'Adhipati' means the lord. 'Dosha' means a blemish. So the name says: a blemish that comes from ruling an angle. It is about the houses a planet rules, not the house it sits in.
Brihat Parashara Hora Shastra states the rule (Brihat Parashara Hora Shastra (Santhanam–Kapoor ed.), ch. 34, vv. 2–7, p. 341). A benefic that rules an angle does not give its good results. A malefic that rules an angle does not stay harmful. Both are pulled toward the middle.
The translator's note adds detail (Brihat Parashara Hora Shastra (Santhanam–Kapoor ed.), ch. 34, pp. 341–343). The natural benefics here are the waxing Moon, Mercury, Jupiter and Venus. The blemish grows in that order, so it is least for the Moon and most for Venus. His example is Mithuna (Gemini) lagna. There Jupiter rules the 7th and the 10th, two angles, and is not counted a benefic. A lagna lord that also rules another angle is not blemished.
For malefics the same book goes one step further (Brihat Parashara Hora Shastra (Santhanam–Kapoor ed.), ch. 34, v. 14, p. 345). A malefic that rules an angle turns good only if it also rules a trine. Otherwise it is neutral. Saturn for Tula (Libra) lagna rules the 4th and 5th, and so is a yogakaraka, not a blemished lord.

- The same book: a malefic angle lord turns good only with a trine; otherwise neutral (Brihat Parashara Hora Shastra (Santhanam–Kapoor ed.), ch. 34, v. 14, p. 345).
- Raman: a benefic turns malefic and a malefic turns benefic, and the change undoes itself when the planet sits in the angle it rules (B. V. Raman, How to Judge a Horoscope, vol. 1, p. 9).
- Nava: neutral in both directions, with no undoing.
- It is about ruling an angle, not sitting in one. A benefic placed in an angle is a different matter.
- The lagna is an angle too, but the lagna lord is not blemished.
- A planet that rules an angle and a trine is a yogakaraka, not a blemished lord.
- Here 'dosha' is a blemish on a planet's role in the chart. It is a classification, not a forecast.
Frequently asked questions
Which planets does kendradhipati dosha touch?
The natural benefics: the waxing Moon, Mercury, Jupiter and Venus. It touches them when they rule an angle from the lagna and are not the lagna lord. The books also pull a malefic angle lord toward the middle, but the name is mostly used for benefics.
Does a benefic ruling an angle become a malefic?
The books differ. Brihat Parashara Hora Shastra says it loses its good and moves toward the middle. Raman goes further: he says it turns malefic, and a malefic angle lord turns benefic. Nava counts both as neutral.
Can the blemish be undone?
Raman says yes, when the planet sits in the very angle it rules. His example is Venus in Tula (Libra) for Kataka (Cancer) lagna. Venus rules the 4th there and sits in it. Brihat Parashara Hora Shastra does not state this. The app does not apply it.
Mithuna and Kanya lagnas: is Jupiter blemished for both?
By the rule, yes. For Mithuna (Gemini) lagna Jupiter rules the 7th and 10th. For Kanya (Virgo) lagna he rules the 4th and 7th. Both pairs are angles and neither is a trine.
Deep dive: two readings, one rule
What the app uses. What to read first.
⚖️ The reading Nava follows
What Nava follows: a planet that rules an angle and no trine, and is not the lagna lord, is counted neutral. This holds both ways: a natural benefic is not turned malefic, and a natural malefic is not turned benefic. The app does not apply Raman's undoing either. Its dasa reading names such a planet as carrying kendradhipati dosha, and reads it as middle-of-the-road. This is a choice between readings of the same rule. Your Period reads the lagna-by-lagna list of Brihat Parashara Hora Shastra (Santhanam–Kapoor ed.), ch. 34, pp. 340–356 instead. Where that list names no verdict, it uses the same chapter's general rules, under which the lord of an angle loses its own nature; like Laghu Parashari, the app counts it neutral.
Raman's two-way reading and his undoing are recorded, not applied. His book is a modern guide to method, and the classical text states only the pull toward the middle.
