Concept
What is KP astrology?
Krishnamurti Paddhati is a 20th-century refinement of Indian astrology. Its big idea is that house cusps, not zodiac signs, do the predictive work.
The cuspal sublord
Every house cusp falls in a sign, in a star (nakshatra), and in a sub. The sub-lord of the cusp is KP's headline idea. It determines whether that house can deliver its results, and what kind. Two charts with identical signs but different sub-lord placements will read very differently.
Sublords, not just signs
Western astrology stops at signs. Vedic astrology goes one level deeper, to nakshatras. KP goes two more levels, to subs and sub-subs. That extra resolution is what gives KP its reputation for specific timing. Minutes-of-arc on a cusp can change a verdict.
House groups, not single houses
KP reads events from groups of houses, not single ones. Marriage is 2-7-11. Foreign settlement is 3-9-12 across three stages. A career change is 5-10-11. The chart has to signify all the relevant houses together, otherwise the event is incomplete.
Ruling planets
Five planets "rule" any given moment: the day lord, the Moon sign lord, the Moon star lord, the Lagna sign lord, and the Lagna star lord. KP uses ruling planets as a real-time confirmation: a predicted event time is only believable if the ruling planets at that moment overlap with the event significators in the natal chart.
Why this matters for your reading
When Lumin gives you a date, it has cross-checked all four layers: promise (sublord), period (dasha), trigger (transits), and confirmation (ruling planets). That is what makes the answer specific, and what makes it possible to verify.
