BhyravKrishnamurti Paddhati (KP) times events by the sub-lord of a house cusp — a division of the zodiac far finer than the sign or even the nakshatra. Each of the 27 nakshatras is split into nine unequal parts in Vimshottari proportion, giving 249 sub-divisions across the 360°. Two people born a few hours apart share a Moon sign and usually a nakshatra, but the seventh-house cusp moves through several sub-lords in that time — and the sub-lord is what KP reads.
The KP rule for marriage
Marriage is promised if the sub-lord of the seventh cusp signifies houses 2, 7 or 11 — family, partnership, and gain of a relationship. If it signifies only 1, 6 or 10 (self, separation, and the house that is twelfth from eleventh), marriage is denied or badly delayed. This is a yes/no test, and it is decided before any timing is attempted.
Where the timing comes from
Once promised, the event happens in the dasha, bhukti and antara of planets that signify 2, 7 and 11 — through their star-lord and sub-lord, not merely by ownership. A planet is a significator of a house in this order of strength: it occupies the star of an occupant of the house; it occupies the house; it occupies the star of the house's owner; it owns the house. The joint period of three such planets, one at each level, is the window, and it is often a few weeks wide.
Then transits confirm: on the day, the Sun, Moon and the dasha lord transit sensitive points — the stars and subs of the significators. This gives a date, not a season.
Why this differs from the Parashari answer
Parashari reads the seventh house lord, planets in the seventh, and Venus, judged by sign strength, aspects and Navamsa. Two people with the same rising sign and Moon sign get essentially the same Parashari reading. KP looks at where the seventh cusp actually falls within its nakshatra — and a shift of ten minutes of birth time can change the sub-lord from Venus (marriage promised, early) to Saturn (delayed, possibly denied). That sensitivity is why KP practitioners insist on rectifying the birth time first.
Ruling planets: the KP shortcut
At the moment the question is asked, KP takes the ruling planets — the lords of the day, the Moon's sign and star, and the ascendant's sign and star at that instant. The event tends to fall in a period ruled by planets common to both the ruling planets and the house significators. It is a quick cross-check that often collapses three possible windows to one.
What to ask for
If a KP reading gives you "Venus–Mercury–Saturn, July to September 2027", it has done its job. If it gives you "Venus period is favourable", that is a Parashari statement wearing a KP label. The sub-lord method produces dates; ask for them.
Common questions
Does KP use the same ayanamsa as Parashari? No. KP uses the Krishnamurti ayanamsa, about six arc-minutes different from Lahiri. Cusps near a sub boundary can shift.
Which house system? Placidus, always. The cusps are unequal, which is what makes the cuspal sub-lord meaningful.
